The Sun took a good aim at Earth this week.
Indeed, on two occasions, an eruption took place very near the central meridian of the Sun. The central meridian is a fixed, imaginary line on the Sun running from the north to the south solar pole. Scientists use this line all the time to unambiguously determine positions of sunspot groups and other solar features on the Sun. The distance to this central meridian is called the "Central Meridian Distance" (CMD). The CMD is negative to the east of the Sun, and positive to the west, and varies between -90° and +90°. If an eruption occurs with a CMD of about 0°, it means the eruption took place very near the central meridian and usually also that it is directed straight towards Earth. Solar orientation grids can be found at various websites, e.g. at SIDC/Soteria (http://www.sidc.oma.be/ ), Solar Monitor (http://www.solarmonitor.org/ ) and at MEES Solar Observatory (http://www.solar.ifa.hawaii.edu/ ). Underneath an example from the SIDC/Soteria page, with the central meridian added as a green dashed line.
The 12 March eruption was associated with a C2-flare that started at 10:17UT and ended only at 12:27UT, making this a long duration event (LDE). The filament belonged to a small sunspot region NOAA 1690. The eruption was at relatively northern latitudes (+/-25°), but part of the ejected material was still directed towards the Earth. From STEREO-B data, it was determined that a coronal mass ejection (CME) had left the Sun with a speed of at least 530 km/s. As predicted, Earth received a glancing blow from this CME resulting in unsettled geomagnetic conditions during the early morning hours of 15 March.
The second eruption occurred on 15 March and started at 05:46UT. It ended at 08:35UT, making it again an LDE. The flare was associated with a filament eruption located very close to sunspot region NOAA 1692, which had already erupted previously during the night of 12-13 March (impulsive C3-flare located about -40° CMD) However, the 15 March flare concerned a M1-flare (weak proton event) located only 10° east of the central meridian, and also a lot closer to the solar equator.
A movie of both eruptions can be seen at http://www.youtube.com/watch?v=P0R20h0B9Yk There is a slight interruption in the movies of the second flare, due to the Earth passing in-between the Sun and SDO. Images underneath depict the respective flares in the combined light of SDO/AIA 335/171, 193, and 304 (corona and transition zone). They show the flares resp. on 12 March at 10:35UT (onset; eruption in progress) and on 15 March at 9:29UT (post-flare coronal loops).
The eruption was accompanied by a considerable solar radio-disturbance that was recorded by the Humain Solar Radio Observatory (image below). It concerns a typical Type IV burst, which is long lasting radio noise due to energetic electrons being trapped in the post-flare loops forming in the aftermath of the eruptive event. Note that the diagonal stripes near the bottom of the figure are due to ground "interference". Indeed, at Humain, the Sun was still at a low elevation in the sky at the time of the event. As such, radio emissions reached the antenna directly and by reflection on the ground, creating these "fringes".
The associated CME had a speed of at least 950 km/s and was of the halo-type, meaning it was heading straight towards Earth. The CME struck our planet in the early morning hours of 17 March, with the speed of the solar wind jumping from about 400 km/s to 750 km/s. More importantly, the CME's magnetic field was quite strong and oriented southward, favoring moderate geomagnetic storming for a good part of the day. The region of good visibility of polar light was limited to the usual places (Scandinavia, Canada, Alaska and northern USA).
Credits - Data, images and movies for this topic were taken from SDO (http://sdo.gsfc.nasa.gov/ ), PROBA2/SWAP and LYRA (http://proba2.oma.be/ ), SOHO/Lasco C3 (http://sohowww.nascom.nasa.gov/ ), SIDC (http://www.sidc.oma.be/ ), STEREO-Behind (http://stereo.gsfc.nasa.gov/ ), ACE (http://www.swpc.noaa.gov/ace/ ) and Humain Solar Radio Observatory (http://sidc.oma.be/humain/index.php ).
The Total Electron Content in the ionosphere was disturbed over Europe on March 17, 2013.
The week started on March 11 with quiet conditions. On Tuesday March 12, the solar activity became eruptive featuring a partial halo Earth bound CME associated with a long duration C2.0 flare from NOAA 1690. On Friday March 15th an M1.2 flare occured and was accompanied by a full halo CME towards Earth. You can check CACTus, the software that detects automatically CMEs inSOHO/LASCO-C2 coronograph: http://sidc.oma.be/cactus/catalog/LASCO/2_5_0/qkl/2013/03/CME0048/CME.html
The GOES proton flux (>=10 MeV) levels increased accordingly on March 15 from 20:00UT and just passed the threshold of 10 pfu on March 16th around 20:00 UT. The flux dropped below the 10 pfu treshold on March 17th around 08:30 UT. It reached normal levels during the second part of March 18.
Geomagnetic activity was quiet to moderate during the week.
Even on Friday March 15 when the CME that left the Sun on Tuesday March 12th arrived. Only a small jump in the solar wind speed, density and temperature was measured by ACE. The Bz component of the interplanetary magnetic field stayed mainly positive. This was the reason why the geomagnetic influence stayed limited. The graph below shows the in situ measurements done by ACE of 4 solar wind parameters on March 15. The top panel is the solar wind speed, the second is the plasma density, the third shows the total magnetic field and the bottom panel shows the Bz component of the IMF.

The figure shows the time evolution of the Vertical Total Electron Content (VTEC) (in red) during the last week at three locations:
a) in the northern part of Europe(N61°, 5°E)
b) above Brussels(N50.5°, 4.5°E)
c) in the southern part of Europe(N36°, 5°E)
This figure also shows (in grey) the normal ionospheric behaviour expected based on the median VTEC from the 15 previous days.
The VTEC is expressed in TECu (with TECu=10^16 electrons per square meter) and is directly related to the signal propagation delay due to the ionosphere (in figure: delay on GPS L1 frequency).
The Sun's radiation ionizes the Earth's upper atmosphere, the ionosphere, located from about 60km to 1000km above the Earth's surface.The ionization process in the ionosphere produces ions and free electrons. These electrons perturb the propagation of the GNSS (Global Navigation Satellite System) signals by inducing a so-called ionospheric delay.

The first Solar Probe Plus Workshop will take place at the
Beckman Institute auditorium, California Institute of Technology,
Pasadena, from March 26th to 29th, 2013. SPP1 will introduce the
Heliophysics community to the mission and prepare for the exciting
discoveries that the Solar Probe Plus mission will make. The
Workshop will explore the scientific objectives of the Solar Probe
Mission and how the direct exploration of the corona and inner
heliosphere will lead to advances in our understanding of coronal
heating and solar wind acceleration, the magnetic and plasma
structure of the heliosphere, and the acceleration of energetic
particles at shocks and flares. The workshop will inspire research
that will make use of the SPP observations within the context of
the NASA Heliophysics Observatory System and identify key areas for
preparatory research. Synergistic observations from other ground
based and space based assets will also be addressed.

The most recent solar minimum, solar cycle 23-24 minimum, was
unusually long (266 spotless days in 2008, the most since 1913),
and the magnetic field at the solar poles was approximately 40%
weaker than the last cycle; and unusually complex (the solar wind
was characterized by a warped
heliospheric current sheet, HCS, and fast-wind
streams at low latitudes: the
fast-wind
threads the ecliptic
more commonly in 2008 than 1996.)
This complexity resulted in many effects observed from Sun to
Earth, with many observations indicating unusual conditions on the
Sun, in the heliosphere
, and in the magnetosphere
, ionosphere
, and upper atmosphere of the
Earth.
This remarkable set of conditions provide the scientific
community with an exceptional opportunity to assess the nature and
structure of a very quiet Sun, and an upper atmosphere relatively
devoid of solar influences, helping to provide a better
understanding of the relative roles of solar activity and internal
variability in the dynamics of the Earth's upper atmosphere and
ionosphere
. Such an understanding requires a
multidisciplinary approach.
The main goal of the conference is to bring together the solar,
heliospheric, magnetospheric, upper atmosphere, and ionospheric
communities to debate and discuss interdisciplinary work and reach
a better understanding of the nature and structure of a very quiet
Sun, and of an upper atmosphere relatively devoid of solar
influences, and in doing so, to help clarify the role of solar
activity in the dynamics and variability of the Earth's upper
atmosphere and ionosphere
relative to the internal
variations.

Solar flares are impulsive releases of energy in the Sun's
corona and yet it is emission from the lower atmosphere (the
photosphere and chromosphere) that contains the bulk of the energy.
This radiation also provides some of the best diagnostics of the
flaring process. The availability of optical, UV/EUV and hard X-ray
observations, made with the current fleet of space-based (SDO,
Hinode, RHESSI, etc.) and ground-based (ROSA, IBIS, Big Bear, etc.)
observatories, combined with recent developments in flare
modelling, presents a timely opportunity to study the cause and
effect of energy deposition in the lower solar atmosphere. The
combination of multi-wavelength observations with advanced
numerical simulations can provide key insights into the processes
of particle acceleration, plasma heating, energy transport, and
wave propagation.
This Royal Astronomical Society discussion meeting will focus on
work investigating the response of the solar and stellar
atmospheres during a flare's impulsive phase and we welcome
contributions from both observation and theory.

Space weather is a new emerging field of space science focused
on understanding societal and technological impacts of the
solar-terrestrial relations. The Sun has tremendous influence on
Earth's space environment, releases energy in the form of
electromagnetic and particle radiation that can damage or destroy
satellite, navigation, communication and power distribution
systems, influence on atmosphere state, magnetosphere and
ionosphere activity. Our workshop IsraSWAPS-2013 will be dedicated
to the origin, evolution and predictability of physical processes
that lead to the space weather hazards. Particular attention will
be devoted to application of plasma physics methodologies and
achievements to space weather problems. The meeting will also focus
on using of plasma understanding as a test bed for astrophysics and
space physics. Contributions in observations, theory, numerical
simulations, and experiment are welcome.

In the last 50 years, helioseismology has made significant
contributions to the knowledge of the Sun's interior physics
and has led the way to asteroseismology. We have now reached an era
where more sophisticated questions are being asked to understand
the subtle properties of the Sun and other stars due to the
synoptic and high-resolution observations available from BISON,
GONG and space missions such as SOHO
, SDO, CoRot and Kepler.
On this occasion, a workshop on the theme of '50 years of the
seismology of the Sun and stars' is being organized to reflect the
progress that has been made as well as to focus on future goals. We
plan to bring together helio- and asteroseismologists, theorists
and observers in a journey that will take us from the interior of
the Sun and its magnetism towards the structure of distant stars
and activity cycles.

Our goal is somewhat different from more familiar conferences
and is designed with the SHINE model in mind. We are inviting very
few speakers who we are asking to give review and introductory
talks for each topic we hope to discuss. Those invited review talks
will be largely non-controversial and focus upon agreed-upon
results. They are also likely to contain challenges for the
participants to explain. Then, the bulk of the time is left
unscheduled and we ask the participants to give short, focused
talks that lead to discussion and debate on the fundamental aspects
of the subject at hand.
We expect that everyone who attends will have ample opportunity
to enter into the debate and we hope to stimulate a lively
discussion of fundamental physics.
We hope you will join us. Bring multiple 5-minute talks that
attempt to make specific points so you can enter into the debate
clearly and propel the discussion forward. No one is expected to be
given a large block of time to speak. The goal is meaningful and
focused debate. Remember, you may not convince everyone, but there
will be many participants who want to understand your point of
view. Our goal is to debate and illuminate, providing inspiration
to all.

climate. A special focus will be on studies of the causes,
consequences and implications of the present, unusually low solar
activity since solar cycle 23 that, most likely, indicates the
imminent end of the Modern Grand Maximum of solar activity. Other
topics include solar dynamo, solar irradiance variations, solar
wind, geomagnetic field and activity, cosmic rays and cosmogenic

Applications are invited for the 2013 Heliophysics Summer
School, which will be held in beautiful Boulder, Colorado. We are
seeking students and undergraduate level teachers and instructors
to join us this coming summer for a unique professional experience.
Students and teachers will learn about the exciting science of
heliophysics as a broad, coherent discipline that reaches in space
from the Earth's troposphere to the depths of the Sun, and in
time from the formation of the solar system to the distant future.
At the same time, a goal of the Summer School is for the group of
instructors to develop materials from Heliophysics that can be
applied in their classes.
The Heliophysics Summer School focuses on the physics of space
weather events that start at the Sun and influence atmospheres,
ionospheres and magnetospheres throughout the solar system. The
solar system offers a wide variety of conditions under which the
interaction of bodies with a plasma environment can be studied:
there are planets with and without large-scale magnetic fields and
associated magnetospheres; planetary atmospheres display a variety
of thicknesses and compositions; satellites of the giant planets
reveal how interactions occur with subsonic and sub-Alfvenic flows
whereas the solar wind interacts with supersonic and super-Alfvenic
impacts.
Encompassed under a general title of comparative magnetospheres
are processes occurring on a range of scales from the solar wind
interacting with comets to the interstellar medium interacting with
the heliosphere. The school will address not only the physics of
all these various environments but will also go into the
technologies by which these various environments are being
observed. The program is complemented with considerations of the
societal impacts of space weather that affects satellites near
Earth and elsewhere in the solar system.
The school will be based on lectures, laboratories, and
recitations from world experts, and will draw material from the
three textbooks Heliophysics I-III, published by Cambridge
University Press.
Several teachers along with about 35 students will be selected
through a competitive process organized by the UCAR Visiting
Scientist Programs. The school lasts for eight days, and each
participant receives full travel support for airline tickets,
lodging and per diem costs.

comprehensive immersion in the subject of space weather: what it
is, what it does, and what can be done about it. Space weather is
many things: beautiful when seen through the eyes of a sun-viewing
telescope, fascinating when studied for its alien worlds of
magnetic structures and phenomena, awesome when witnessed as a
solar eruption or auroral storm, and devastating to the users of
services it disrupts. Space weather links the Sun, the Earth, and
the space in between in a branching chain of consequences. Weather
systems on the Sun can spawn interplanetary storms of colossal size
and energy that envelop the whole planet in electrical hurricanes.
Such storms attack high-tech, complex, and expensive technological
systems that provide much of the infrastructure that allows modern
society to function.

The goal of this workshop is to foster collaborations between
ground and space solar projects. This workshop is expected 1) to
provide a forum to discuss the use of current and future
observational solar facilities, and how to optimise their
scientific returns; 2) to identify the potentially
paradigm-shifting observations that will become possible with the
next generation ground- and space-based solar telescopes and their
advanced instrumentation; 3) to foster collaborations between
researchers working at the development of ground- and space-based
projects and creation of synergies between research programs at
different wavelength bands.
A workshop webpage and more information will follow shortly -
the purpose of this pre-announcement is to enable early bookings in
your calendar.

The Local Organising Committee and the Mexico National Committee
of IUGG have the great pleasure to welcome you to the 11th
Scientific Assembly of the International Association of
Geomagnetism and Aeronomy (IAGA) which is held in Mérida
Yucatán, Mexico from 26 to 31 August 2013 with the
motto: "Living on a Magnetic Planet". Our Magnetic Planet
Capricious (Changeable or Unpredictable) Field.
In order to increase the visibility and attractiveness of IAGA
to young researchers, to motivate them to play active role within
IAGA and to create (and enhance) their awareness of IAGA and sense
of belonging to IAGA, the first IAGA Summer School will be
organized just prior the Assembly. The summer school will provide
overview of the activities carried out within all the IAGA
divisions, with subjects from paleomagnetism and magnetic
anisotropy through observatories and geomagnetic field modeling to
ionospheric and aeronomic research. At least 20 young scientists
from all around the world will be invited based on the nominations
from Working Groups and Divisions. Special call and more
information will be published before the end of 2012.

This conference will focus on instrumentation, observatories,
space missions, and programs for observations from the Sun to
Earth's upper atmosphere and space environment. The aim is to bring
together diverse communities working on all elements of solar
physics and space weather instrumentation.
Studying solar phenomena and monitoring space weather requires
observations using both space- and ground-based instrumentations
covering the different regions of the Sun-Earth system, the Sun,
interplanetary medium, magnetosphere, ionosphere, and thermosphere.
Papers are solicited concerning all instrumentation-supporting
solar physics and space weather. This includes, but is not limited
to, concepts, designs, fabrication processes, calibration, data
trending, information technologies, solar data mining, instrument
modeling, and satellite lifetime prediction modeling. We are also
interested in all past, current, and future solar space missions
and satellite and ground constellations of space weather
instrumentation with a strong focus on Space Situational
Awareness.
This conference is intended to provide the solar physics
community and that of Earth's space environment with a forum for
discussing the latest updates on instrumentation, observation
techniques, and programs in their respective fields, and for
proposing innovative ideas for future Sun-Earth coordinated
observations.

We gain information about the universe through analysis of the
spectra from celestial objects. However, while the intensity
spectrum represents a scalar quantity but electromagnetic radiation
occurs in the form of transverse waves, the polarized spectrum
provides us with a 4-vector, the Stokes vector. The increased
amount of information space opens new windows to the universe, in
particular for the exploration of magnetic fields. It is well
recognized that the magnetic field is a primary agent responsible
for structuring and the source of all variability on intermediate
time scales, which manifests itself in all forms of solar and
stellar activity.
It is therefore not surprising that every year there are many
scientific meetings organized with the objective of studying the
role of magnetic fields in cosmic objects. What is largely missing
in these meetings is however an in-depth investigation of the
fundamental aspects of how magnetic fields can be determined by the
means of spectro-polarimetry, our main gateway to cosmic magnetism.
The primary aim of our series of Workshops is to address these
fundamental aspects, with less emphasis on the morphological and
physical properties of cosmic magnetic fields.

The meeting will cover a broad range of aspects of solar
physics, space science and solar-terrestrial relations. We aim to
include every side of solar and space research, including
observations, theory, and numerical modelling. The main idea behind
the meeting is to treat the entire solar-terrestrial domain as one
system, rather than each region independently.
The topics to be covered are:
* advanced solar observations
* waves and flows in the Solar atmosphere
* structure and dynamics of solar magnetic fields
* connecting analytical theory and modern numerical simulations
to observations
* new physics in numerical modelling
* linking solar interior with heliosphere
* particle acceleration in the Sun and heliosphere
* non-linear phenomena in space plasmas
* physics of magnetosphere and ionosphere

This summer school targets to introduce a generation of young
researchers (advanced master students, PhDs, and junior
postdoctoral researchers) to the diverse aspects of space weather
related research.
It will introduce theoretical approaches to space weather and
its drivers, present modern solar data analysis tools, and cover
state-of-the-art solar and space science simulations. Participants
will learn about forecasting aspects and their quality control for
space weather events, but also experience hands-on training in
scientific proposal writing and receive do-and-don't tips for
scientific presentations.
The scientific program is enriched by a public evening lecture
on the solar influence on our climate, and the lecturers are
invariably expert scientists with international standing.
The school is open to a maximum of 40 participants, and can
benefit from its embedding within two international research
network activities: an Interuniversity Attraction Pole P7/08 CHARM
connecting heliospheric to astrophysical communities with 7 partner
institutes, and a European FP7 Project eHeroes with 15 different
partner institutes. Participation from outside both network
activities is strongly encouraged. Within Belgium, the school links
up expertise from universities (KU Leuven, ULB, Gent University) to
federal research institutes (the Solar-Terrestrial Centre of
Excellence, the Royal Observatory of Belgium and the Belgian
Institute for Space Aeronomy).

Since its launch in Sep-2006, more than 600 refereed papers have
been published based on Hinode observations, presenting many new
and important findings to the scientific community. However, due to
the unexpectedly low levels of solar activity, until now the focus
has mainly been on the more quiescent aspects of the solar cycle.
With the solar maximum expected this year, through cooperative
observations with SDO, IRIS, and ground based observatories, Hinode
observations should lead to our understanding of active Sun
phenomena, such as solar flares and CMEs, to be greatly improved.
Making Hinode-7 an excellent opportunity to discuss solar activity
in the current solar cycle and the related science through the use
Hinode data, as well as other solar/space weather data. It will
also be interesting to use this meeting to broaden our focus to
include the solar-stellar connection as a means to deepen our
understanding of solar activity.
Momentum is also gaining for Solar-C, which is being developed
as an international collaboration between Japan, US and Europe. To
further discuss this mission, the Solar-C science meeting will be
held on 11-Nov.

This International CAWSES-II Symposium hosted by SCOSTEP
(Scientific Committee on Solar-Terrestrial Physics) will provide an
excellent opportunity to discuss the scientific accomplishments of
CAWSES-II and look forward to SCOSTEP's future programs at a moment
toward the end of its five-year period. The symposium will cover
the six major themes of CAWSES-II tasks: 1) What are the solar
influences on the Earth's climate?, 2) How will geospace respond to
an altered climate?, 3) How does short-term solar variability
affect the geospace environment?, 4) What is the geospace response
to variable inputs from the lower atmosphere?, 5) Capacity
Building, 6) Informatics and eScience. The main functions of
CAWSES-II are to help coordinate international activities in
observations, modeling, and applications crucial to achieving this
understanding, to involve scientists in both developed and
developing countries, and to provide educational opportunities for
students of all levels. The symposium offers keynotes/lectures that
will be interesting for all participants every morning and more
specific sessions of presentations in the afternoon. We welcome all
those who are involved and/or interested in CAWSES-II to Nagoya in
the autumn when we will have the pleasure of being surrounded by
beautiful colorful leaves of this season.
