NOAA Active Region 1520 certainly was a very active sunspot group. During its transit across the solar disk, it produced 5 M-class solar flares and even one X-flare (the strongest class). When it crossed the solar limb on 18 July, it certainly didn't diminish in activity. Indeed, over the next few days, several coronal mass ejections could be seen billowing away from behind the solar limb.
A particular interesting event occurred in the early morning hours of 23 July, when this active region produced another eruption. At that time, NOAA 1520 was already several days on the backside of the Sun, and no instruments from Earth could monitor the blast in x-ray or radio-wavelengths.
However, the STEREO-A satellite was well positioned to observe this event. Together with its twin brother STEREO-B, these spacecraft are orbiting the Sun in such a way that they gradually get a better view of the Sun’s backside (http://stereo.gsfc.nasa.gov/beacon/ ) . The schematic underneath shows which part of the solar surface was visible from Earth (green), from STEREO-A (red), and from STEREO-B (blue). As can be seen, the flare was directed almost straight towards STEREO-A, and occurred very close to the “east” limb for STEREO-B.
The flare itself occurred around 02:30UT in the morning, following some magnetic activity that had already been going on for an hour. From the brightness and the extent of the eruption, one can safely conclude that this was a high energetic event, probably belonging to the strongest X-class of solar flares.
The ejection of material left its mark in the Sun's corona, being visible as an irregular dark hole to the bottom left of the flare. The ejected cloud was visible in images from SDO (http://sdo.gsfc.nasa.gov/ ), PROBA2 (movie at http://proba2.sidc.be/swap/data/mpg/movies/20120723_swap_movie.mp4 ), SOHO http://sohowww.nascom.nasa.gov/ , and both STEREO-satellites. STEREO-A saw this ejected material as a full halo emanating from the Sun, indicating that this particle cloud was on a collision course with the tiny spacecraft.
Even though the source of the eruption was behind the limb as seen from Earth, bright, hot post-flare loops of magnetic field, tell-tale markers of the magnetic activity that drives coronal eruptions, were soon visible rising high above the solar surface.
The powerful flare also produced what space weather experts call a proton event, generating a stream of high energy protons reaching STEREO-A in just a few hours. Starting at about 10:30UT, these high energy particles interfered with the spacecraft’s onboard electronics, significantly degrading the quality of images from STEREO-A. Some of these protons managed to make it all the way to the Earth, causing a very weak proton event. This is not an uncommon occurrence, as –in the past- there have been other events so far on the Sun’s backside to produce proton effects here on Earth.
The most interesting part of this eruption, again testifying of its rare strength, occurred during the evening hours of the very same day. Indeed, the coronal mass ejection (CME) arrived at STEREO-A already around 20:00UT, with solar wind speed jumping from about 550 km/s to at least 1400 km/s. When a CME travels the Sun-Earth distance (in this case Sun - STEREO-A) in less than 22 hours, it gets a special name: Fast Transit Event. Only a handful of such events are known, and they are associated with severe geomagnetic storming. One of the last such events were the CME's from the Halloween events (29-30 October 2003), when speeds (near Earth) were recorded in excess of at least 1850 km/s, having travel times of about 19 hours.
Of course, one could ask with which speed the CME took off at the Sun. As a CME is usually decelerated by the much slower solar wind around it, this CME must have had a much higher speed than the 1400 km/s it had at STEREO-A. Usually, scientists take some key-points along the CME's outskirts to determine its speed. This is always a tricky case, because when the CME is traveling along the line-of-sight, the eruption's apparent speed might be significantly less than the true speed (see schematic underneath). With NOAA 1520 already well beyond the solar limb, this line-of-sight effect had a significant influence on the measurements by SOHO. STEREO-B on the other hand was best placed for this kind of calculations.
Combining images from the spacecraft (SOHO, STEREO-A and -B) in an advanced triangulation matrix, scientists from NASA’s Space Weather Research Center (SWRC - http://swc.gsfc.nasa.gov/main/20120723-AL-005 ) were able to calculate the initial speed of the CME to be about 3400 km/s. Such a speed places it in the hall of CME's with the highest initial CME speed ever, comparable e.g. to the 20 January 2005 event. A performance worthy of a true Olympian!
The week started with an event with a potential impact: active region 1520 was the source of a CME which caused CACTus (software for automated CME detection in LASCO coronograph images) to send a halo CME-alert. The picture below is a difference image: two pictures are subtracted from each other such that the differences between them become clear and the similarities are not shown. Moving structures pop up in a clear way in difference images. These images are made by LASCO, a coronograph onboard the spacecraft SOHO.
A sector boundary crossing caused unsettled conditions on July 23-24: the interplanetary magnetic field (IMF) oscillated such that the Earth passed from a region to another with a magnetic field pointing in the opposite direction.
A magnetic structure was visible in the solar wind on July 28 - see the top panel of the picture below. The structure had a speed of 350 km/s - see the fourth panel of the picture.
Solar Activity
Early this week, the Sun's activity level was generally *low* until AR 11532 crossed the East limb Thursday.
In order to view the activity of this week in more detail, we suggest to go to the following website from which all the daily (normal and difference) movies can be accessed: http://proba2.oma.be/ssa.
This page also lists the recorded flaring events.
On Monday 23rd, AR11520, from behind the West limb, expelled a very rapid CME. According to some reports this could be the fastest CME ever recorded, with an ejection speed of around 3400 km/s.
A movie, showing the phenomenon can be found here:
http://proba2.oma.be/swap/data/mpg/movies/campaign_movies/2012_07_23_01_50_08_2012_07_23_02_49_44_SWAP_174__AIA_304.mp4
The movie was generated with HelioViewer, using (colored) SWAP (174, yellow) and SDO AIA (304, orange) images.
One image of the movie is shown below:

On Thursday 26th, an extended filament eruption occurred on the north east limb.
A movie, showing the phenomenon can be found here:

This movie was generated with HelioViewer, using (colored) SWAP (174, yellow) images. Right after the end of this eruption, another filament eruption occurred on the opposite side, i.e. on the north west limb, starting after midnight on July 27th.
Some (original, uncolored) SWAP pictures of this eruption are shown below:
1. Eruption in progress
2. Eruption at maximum extension
SWAP Image: Filament eruption on Thursday 26/07; at 22:24

On Saturday 28th, several spectacular phenomena occurred.
Filamenent/prominence activity could be followed from Saturday 28th around 15:00 until Sunday 29th 03:00, starting near the south east limb and evolving into on disk filament activation between AR 11530 (southern) and AR 11528 (northern). Also on July 27th such a (more reduced) filament brightening occurred.
Several SWAP (and SDO) movies about these phenomena can be found in the following directory: http://proba2.oma.be/swap/data/mpg/movies/campaign_movies/2012_07_272829/
The following pictures (combined SWAP 174 in yellow and SDO 304 in orange) show the evolution of:
1. the swirling filament eruption having started near (or possibly behind?) the south east limb
2. the end of the eruption and the start of the filament brightening between ARs 11530 and 11528.
3. the filament brightening at its brightest
Below, a SWAP (normal and difference) image of the filament brightening:
From Friday to Sunday, AR 11532 generated 1 M flare per day
An M6.1 flare occurred on Saturday. A SWAP picture around 21:00 and the associated LYRA/GOES curves are shown below:

You will have a noticed the slight re-branding of these
workshops from 'Image' to 'Information' processing. We think it is
time to expand the attention of these workshops to discuss more
generally how information about the Sun can be derived, stored,
shared, transformed and analyzed using appropriate techniques from
many other disciplines. We will still be covering image processing
and computer vision techniques applied to solar physics, but we
will also be including other topics such as machine learning, data
mining and new computing strategies. The re-branding simply
acknowledges and makes explicit what the community has been doing
to determine the physics of the Sun.

We are pleased to announce the Fermi Solar Data Analysis
Workshop to be held at Goddard Space Flight Center on August 22-23,
2012. Although primarily an Astrophysics observatory, the Fermi
Gamma-ray Space Telescope, and its Gamma-ray Burst Monitor (GBM)
and Large Area Telescope (LAT), provide unique capabilities in the
8 keV - 300 GeV band to monitor and study both the quiescent and
flaring Sun. Fermi has already made many observations of solar
X-ray and gamma-ray emissions, and many more can be anticipated
during the next few years with the peak in solar activity expected
in 2013.
This workshop is meant to be informal and interactive. It will
start with reviews of X-ray and gamma-ray solar studies to date,
including results already obtained with the Fermi observatory.
Extensive tutorials will be given on both GBM and LAT data analysis
techniques, with time set aside for hands-on practice on your own
laptop. We invite all of those interested in learning more about
Fermi's Solar capabilities, and interested in interacting with
experts in the field, to attend this 2-day workshop.

The Fourth HELIO Coordinated Data Analysis Workshop (CDAW) will
be held during September 2012 in the School of Physics of Trinity
College Dublin.
The purpose of this CDAW is to provide an opportunity for the
heliophysics community to learn about the capabilities of HELIO and
discover how they can be used to address science use cases.
Feedback from the CDAWs also help us determine how the HELIO
infrastructure should be extended.
The goal of the workshop is to exercise the HELIO infrastructure
based on a selection of use cases and verify of the functionality
of the services and their level of integration.
The general objective is to exercise the infrastructure by
studying use cases that require observations made at multiple
points in the Solar System, as e.g. propagation studies of CMEs and
SEPs from their solar source toward 1 AU and beyond.
One specific objective is to examine how well the propagation
tools that we are developing actually help determine the timing of
the required remote sensing and in-situ observations. This will
help us identify what improvements and developments are required
for this capability.

The International Space Weather
Initiative (ISWI) is a program of
international cooperation to advance the space weather
science by a combination of
instrument deployment, analysis and interpretation of space weather
data from the deployed instruments
in conjunction with space data, and communicate the results to the
public and students. ISWI is a follow-up activity to the successful
IHY 2007, but focusing exclusively on space weather
. The goal of the ISWI is to
develop the scientific insight necessary to understand the science,
and to reconstruct and forecast near-Earth space weather
. This includes instrumentation,
data analysis, modeling, education, training, and public outreach.
ISWI has conducted many programs not only to popularise space
science all over the world but also to create favorable conditions
for joint research and training in some sort of global framework.
In the framework of IHY and ISWI, some research groups have been
established in several countries. In order to establish the strong
space research group, particularly in Asia-Oceania countries, a
training to the young students and researchers is necessary. In the
framework of this program, the Space Science Center of National
Institute of Aeronautics and Space (LAPAN) is honored to host the
2012 ISWI and MAGDAS School in Space Science, the school to young
solar physicists and geophysicists, to be held on 17-26 September

The 2012 Solar Radiation and Climate Experiment (SORCE) Science
Meeting examines modeling efforts to understand solar spectral
irradiance (SSI) variability, in terms of both its origins in the
solar atmosphere and its impact on Earth's climate and atmosphere.
In solar physics, advancements in radiative transfer, surface
feature identification, dynamics and how observations of solar
magnetic fields and irradiance all lead to an improved
understanding of the mechanisms of irradiance change.
Earth-atmospheric general circulation models (GCM) incorporating
sophisticated codes for chemistry, radiation, dynamics, and
feedback mechanisms associated with clouds, aerosols, and ocean
processes are able to address the role of SSI variability in
climate. In both cases, comparisons with observations lead to a
deeper understanding of the dynamic solar atmosphere and our
complex Earth climate system.

Initiated in 1990, the United Nations Basic Space Science
Initiative (UNBSSI) has contributed to the international and
regional development of astronomy and space science through annual
workshops organized under the umbrella of the United Nations,
focusing specifically on the International Heliophysical Year 2007
(IHY, 2005-2009) and the International Space Weather
Initiative (ISWI, 2010-2012).
UNBSSI has led to the establishment of planetariums, astronomical
telescope facilities, and IHY/ISWI instrument arrays worldwide,
particularly in developing nations. ISWI is envisioned to continue
the tradition of IHY in the worldwide deployment of space weather
monitoring instrument arrays. To
date, ISWI contributes to the observation of space weather
through 18 instrument arrays with
close to 1000 operating instruments in more than 100 nations
supported by designated national ISWI coordinators.
The first workshop on ISWI was held in Helwan, Egypt and hosted
by the Helwan University, Egypt, in 2010, particularly for the
benefit of nations in Western Asia. In 2011 the United
Nations/Nigeria Workshop on ISWI was hosted by the Centre for Basic
Space Science of the University of Nigeria at Nsukka, Nigeria,
particularly for the benefit of nations in Africa. The third ISWI
workshop will be hosted by Ecuador in 2012 for the region of Latin

2012 - 2013 is expected to be years with high solar activity.
This can trigger larger solar storms which can generate geomagnetic
induced currents (GIC
) on the earth. GIC
can affect the normal operation of
specific industrial operations and critical infrastructure (e.g
power grids, telecom, navigation systems, etc).
During space weather
events, like solar storms, electric
currents in the magnetosphere
and ionosphere
experience large variations, which
manifest also in the earth's magnetic field. These variations
induce currents (GIC
) in conductors operated on the
surface of the earth. Electric transmission grids and buried
pipelines are common examples of such conductor systems. GIC
can cause problems, such as
increased corrosion of pipeline steel and may disturb and possible
damaged high-voltage power transformers and it can also have
damaging effects on communication systems, navigation systems and
oil and gas operations.
Vulnerable industries are the oil and gas industry, railways,
telecommunication industry, navigation industry and not at least
the society, which is very vulnerable concerning short or long term
interruption of critical infrastructure.
The conference will focus on increasing the general knowledge of
solar storms, space weather
and GIC
and the possible consequences for
different industries and critical infrastructure, and look into
reasonable means of protection, and consider possible early warning
solutions.

The International Symposium on Solar-Terrestrial Physics will be
held during November 6 - 9, 2012 at the Indian Institute of
Science, Education and Research, Pune, India. This meeting under
the aegis of the SCOSTEP is expected to draw leading scientists
from around the world in the increasingly important,
interdisciplinary fields of Solar activity and its impact on
geospace and life on the Earth. With major observational solar
facilities being planned in India, this meeting is especially
pertinent in the Indian context.
The meeting is expected to involve professional scientists as
well as graduate students, and will have a mixture of invited and
contributed talks and posters. There will also be a one-day
tutorial for the benefit of young people beginning work in the
field of solar-terrestrial physics.

As we emerge from one of the deepest and longest solar minima on
record, with a new and powerful eye on the Sun -SDO- we invite all
those with an interest is solar activity to gather in beautiful
Palm Cove, Australia to review and assess our current knowledge and
understanding of our magnetic star
, and to experience the awe and
wonder of a total solar eclipse on November 14, 2012.

The European Commission will organise the 'Let's embrace
space - FP7 Space Conference 2012', in cooperation with the Cypriot
EU Presidency, on 15 and 16 November 2012 in Larnaca, Cyprus.
This scientific conference will present the current status and
results of the 3rd call of FP7 space research, and also discuss
future options for European research in the space field. In doing
so, the conference will aim at demonstrating the evolution and use
of space tools for a sustainable economic and environmental
development in a European and global context.

Nobeyama Radioheliograph (NoRH) has been observing the Sun since
1992. This year is the 20th year of science operation. Instruments
are still in good shape and producing images of the Sun every day
with the same quality as the beginning. Due to the nature of the
instrument and long and uniform observations, data can be used for
wide variety of solar physics and also for solar terrestrial
physics. To mark the 20 years of operation, we will organize a
symposium to summarize what has been done with NoRH and to discuss
what we should do in the future. Papers to be presented in the
meeting will be mainly concerned with the results from NoRH and
future plans.

Spacecraft observations have established that all magnetized
planets in our solar system interact strongly with the solar wind
and possess well-developed
magnetotails. Magnetotails are the site for many dynamic processes
critical to the circulation of mass, energy and magnetic flux. The
great differences in solar wind
conditions, planetary rotation
rates, ionospheric conductivity, and physical dimensions from
Mercury's small magnetosphere
to the giant magnetospheres of
Jupiter and Saturn provide an outstanding opportunity to extend our
understanding of the influence of these factors. Therefore, this
Chapman conference will provide a forum in which various
communities can come together and discuss recent achievements of
observational, theoretical, and modeling studies with the objective
to develop a deeper understanding of fundamental properties and
processes of planetary magnetotails through a comparative
examination.
