Press release 22 May 2015 09:10 - Seismology-Gravimetry/ROB
at 03h52 (local time) near Ramsgate, Kent (United Kingdom).
Because of the relative large depth, estimated on 15 km, no damage was seen near the epicentre. But the earth quake was felt in an area, more than 250 km from the epicentre.
If you felt the earth quake, please fill in an online form http://www.seismologie.be
Your input is an important source of information for the research of earth quakes in our region.
This earth quake took place 24 km north east from an earth quake in Folkestone on 28 April 2007 with magnitude 4.3. Also in 1382 and 1580, some devastating earth quakes took place in the Southern part of the North Sea and Pas-de-Calais with an estimated magnitude of 6.
Some very nice prominence and filament eruptions were observed over the last week. In this movie at https://youtu.be/IwbWeXTFfEs, four major events are shown in the combined filters of SDO's (http://sdo.gsfc.nasa.gov/) AIA 304 ("cool"; about 80.000 degrees; red) and AIA 193 ("hot"; about 1.3 million degrees; green). Prominences and filaments usually lay dormant until the surrounding magnetic fields become unstable and eject the material into space. As the plasma traces the untwisting magnetic field lines, it often shows an helical ("corkscrew") motion. More info on these features can be found in e.g. the news items at http://stce.be/news/302/welcome.html , http://stce.be/news/297/welcome.html , and http://stce.be/news/281/welcome.html
The first eruption took place early on 09 May near the northeast solar limb and was associated with a C7.4 flare peaking at 01:34UT. It was also preceded by a filament eruption in the northeast quadrant, which may have triggered the limb event. The movie clip covers both eruptions and runs from 08 May at 23:30UT till 09 May at 03:30UT. Earth was not affected by the associated coronal mass ejection (CME).
The second eruption took place on 12 May at the west limb and was associated to a C2.6 flare peaking at 03:02UT. The clip covers the event from 01:30UT till 04:30UT. The event enhanced the greater than 10 MeV proton flux (energetic particles), but the flux remained below the alert threshold.
On 13 May, a filament erupted in NOAA 2345, close and to the east ("left") of big active region NOAA 2339. It was associated with the strongest flare of last week, a C9.2 flare peaking at 18:18UT. The bulk of the CME was directed to the north, but a faint full halo CME could be distinguished in difference images made by SOHO's LASCO/C2 coronagraph (http://sohowww.nascom.nasa.gov/). Moving very slowly, it either passed the Earth unnoticed or got mixed with the arrival on 18 May of the high speed stream of a nearby recurrent coronal hole.
In the night of 15-16 May, a long and dynamic filament impressively erupted near the northeast limb. A few hours later it was followed by the eruption of a nearby, much smaller filament to the west. No obvious flares were associated with these events, and the CMEs had no earth-directed component.
Solar flare activity fluctuated between very low and low during the week.
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:

NOAA 2339, the largest and magnetically most complex sunspot region on the visible solar hemisphere, produced 19 of this week's 32 C-class flares. No M-class flares were recorded.
NOAA 2345 produced the strongest flare of the period, a C9.2 flare peaking on 13 May at 18:18UT. It was associated with a faint and slow-moving halo coronal mass ejection (CME), which was still awaited to arrive at Earth on 18 May, but with only unsettled to active geomagnetic disturbances expected.
Numerous filament and prominence eruptions were observed, but none of these had an earth-directed component. A prominence eruption that took place on 12 May (C2 flare peaking at 03:02UT) at the southwest limb was associated with a mild enhancement of the greater than 10 MeV proton flux. A peak of 6 pfu was recorded on 12 May around 07:30UT, staying well below the proton event threshold.
Another noteworthy eruption was that of a long and dynamic filament near the northeast limb late on 15 May, without consequences for the Earth.
On 12 May around 18:00UT, a high speed stream from a negative polarity coronal hole (CH) - green encircled in SDO/AIA 193 image - started to influence the geomagnetic field. Solar wind speed gradually increased to 750 km/s, with Bz-values up to -14 nT recorded.
It resulted in active (Dourbes) to moderate storming conditions (Kp=6) on 13 May. From 14 May onwards, only quiet to unsettled geomagnetic conditions were observed. A sector boundary crossing (SBC) occurred on 17 May shortly after 04:00UT, with the direction of the interplanetary magnetic field abruptly changing from towards to away from the Sun.
The event had little bearing on the geomagnetic field. The high speed stream from a positive polarity CH that passed the central meridian on 14-15 May was still awaited to arrive at Earth on 18-19 May, with limited geomagnetic impact (active conditions) expected.
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 last five years have seen substantial progress in our
understanding of the solar dynamo, fueled by continuing advances in
observations and modeling. With the launch of NASA's Solar Dynamics
Observatory (SDO) in 2010 came an unprecedented window on the
evolving magnetic topology of the Sun, highlighting its intricate
3D structure and global connectivity. The Helioseismic Magnetic
Imager (HMI) instrument on SDO in particular has provided
potentially transformative yet enigmatic insights into the internal
dynamics of the solar convection zone that underlie the dynamo.
Attempts to detect subsurface convective motions from helioseismic
inversions have yielded only upper limits on the large-scale
convective amplitude, challenging our understanding of global solar
convection. Yet, potential signatures of giant cells have been
detected in photospheric Dopplergrams. Estimates of the meridional
flow from HMI and complementary instruments (SOHO/MDI and GONG)
have been equally tantalizing and enigmatic. Several disparate
techniques, including local and global helioseismic inversions and
correlation tracking of surface features, have yielded evidence of
a multi-cellular meridional flow but they differ on the detailed
flow structure and amplitude. This multi-cellular meridional flow
has potentially profound implications for flux-transport dynamo
models that previously assumed a very different structure with a
single circulation cell per hemisphere.

We would like to invite you to submit contributed abstracts to
the parallel session "The science of space weather: progressing our
understanding" at the 2015 UK National Astronomy Meeting from 5-9
July (http://nam2015.org). The abstract-submission deadline is 1
April 2015. Observers, modellers, and theoreticians are all
welcome. We also welcome participation from end users interested in
how the science of space weather is advancing.
The science of space weather: progressing our understanding
The goal of this session is to provide an opportunity to discuss
the scientific research that underpins space weather and how a new
generation of operational space weather measurements could best be
utilised to further progress our understanding. Specific topics are
likely to include 1) gaps in our understanding of space weather and
how to resolve them, 2) new space and ground-based data that are
needed, 3) new science that can be carried out with the operational
space weather measurements being planned today.
This session is motivated by the fact that the UK has a strong
heritage in the science of the coupled Sun-Earth system, from both
an observational and theoretical perspective. This research is
increasingly being applied to the area of space weather monitoring
and forecasting, a topic that is now nationally recognised as an
important natural hazard for the UK (highly ranked in the National
Risk Register) and the subsequent opening of the Met Office Space
Weather Operations Centre in 2014.
Up until now, both the research and the space weather monitoring
and forecasting have utilised mainly data from instrumentation
(both space- and ground-based) designed to answer pertinent
scientific questions, though some operational instruments (e.g. the
X-ray and particle detectors on NOAA's GOES spacecraft) are also
widely exploited for scientific use. However, there is now growing
interest in deploying more instruments, in space and on the ground,
designed to support operational space weather services. Such
operational measurements can facilitate new science, as
demonstrated by the extensive research use of GOES data, but it is
important that the limitations imposed by operational needs are
discussed.

The CISM Summer School is intended to give students a
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 International Workshop and School on solar system plasma
turbulence, intermittency and multifractals (STORM 2015) focus on
the quantitative experimental, theoretical and numerical
investigation of turbulence, intermittency, fractal/multifractal
features, waves and coherent structures interaction, criticality
and non-linear cross-scale coupling. As widely documented by
in-situ satellite measurements and remote or ground-based
observations, turbulence, intermittency and dynamical complexity
are quite ubiquitous processes observed in the dynamics of solar,
planetary and interplanetary plasmas, as well as in the dynamical
evolution of proxies linked to magnetospheric and ionospheric
variability.
Unfolding the spatio-temporal structure of magnetic field and
plasma fluctuations from experimental observations and numerical
simulations provides further insight on the structure of plasma
turbulence and intermittency. On the theoretical side, the
understanding of such complex dynamical behavior cannot be simply
surmised from the basic fluid/kinetic equations, but instead
requires novel theoretical, experimental and data analysis
approaches. The workshop is a forum to present and discuss latest
results in these fields. The purpose of the school is to give to a
young audience of Graduate, Ph.D. students, and postdoc scientists,
which ideally represents the next generation of scholars in the
physics of space plasmas, an overall view of both theoretical and
data analysis tools apt to fully exploit unique and unprecedented
observations that will be provided by future upcoming mission like
Solar Orbiter and Solar Probe Plus.

fundamental to modelling the influence of solar variability on the
Earth's environment and climate. To capture all the physical
aspects of the solar wind-magnetosphere-ionosphere-atmosphere
interaction, and also the impact of solar variability on climate,
the Sun-Earth system has to be studied as a whole. The main purpose
of this school is to provide graduate, PhD students and also young
post-doc researchers with a global view of the main physical
processes by which solar variability affects the Earth's
environment. In addition, an overview of different data analysis
and methods for describing solar-terrestrial relations will be

This CSPM-2015 scientific meeting will cover various aspects of
solar dynamic and magnetic phenomena which are observed over the
entire electromagnetic spectrum: white-light, Hα, Ca II,
and radio from ground and in a variety of other wavelengths (white
light, UV and EUV, and X-rays) from space. Emphasis will also be
placed on instrumentation, observing techniques, and solar image
processing techniques, as well as theory and modelling through
detailed radiative transfer in increasingly realistic MHD models.
The long-term (cyclic) evolution of solar magnetism and its
consequence for the solar atmosphere, eruptive phenomena, solar
irradiation variations, and space weather, will be in focus. Here,
special attention will be devoted to the long-term observations
made in Coimbra and also to the results of the SPRING / SOLARNET
and SCOSTEP VarSITI studies. In particular, the weak solar activity
during the current solar maximum will be discussed. Finally, since
this meeting is organised around the 90th anniversary of performing
the first spectroheliographic observations in Coimbra, a session
will be specially dedicated to new solar instruments (both
ground-based and space-borne) that will give access to unexplored
solar atmospheric features and dynamic phenomena over the coming

The workshop aims to gather experts from the various fields of
remote sensing observations of the inner heliosphere,
including white light, EUV, and radio observation,
together with modellers in order to tackle key outstanding science
and space weather operational issues, establish closer
working relations, and devise the best ways to move the field
forward as a whole. In addition, the science learned from remote
Âsensing observations is critical to improving our
capabilities of space weather forecasting. The workshop
aims to look at ways in which we can more easily and efficiently
share and access the various types of data between individual
groups and subÂcommunities and to officially launch the
IPS Common Data Format v1.0 (IPSCDFv1.0) now in use. It also aims
to allow investigations into ways in which we model the inner
heliosphere looking at the advantages and disadvantages of the
available modelling, updates on present and future
remoteÂsensing capabilities, and investigating further
the ways in which these data sets all complement each other and are
necessary to gain knowledge and understanding of the fundamental
physical processes that occur within the inner heliosphere. These
are critical processes that are key to both Heliophysics science as
well as to spaceÂweather operations and forecasting.

The scientific goal of this symposium is to discuss recent
results on the processes shaping the structure of the solar
atmosphere and driving plasma eruptions and explosive events.
Activity of the solar atmosphere entails numerous multi-scale
processes. State-of-the-art solar instrumentation is revealing the
dynamics of the Sun with unprecedented temporal and spatial
resolutions. Together with advanced numerical simulations these
investigations are making new steps in our understanding of the
complex dynamical structure of the solar atmosphere.
Major unsolved problems of astrophysics such as how the solar
corona is heated and how the solar wind and heliosphere are powered
have their roots in the origin of small-scale magnetic fields
constituting the Sun's 'magnetic carpet' in the
photosphere and appearing as 'magnetic canopy' in the
chromosphere.
