In the afternoon of July 12, 2012, the complex and up-to-then relatively quiet sunspot group NOAA 1520 all of a sudden produced an extreme solar flare.
The X1.4 flare started at 15:37UT, reached its peak at 16:49UT, and ended at 17:30UT, making it a long duration event. It is only the 14th X-class flare recorded so far in solar cycle 24 (SC24). Being already in the 42nd month, this is a low number of X-flares compared to the previous solar cycle 23 (22) or to SC22 (73, and already past its cycle maximum!). The 12 July flare and subsequent coronal mass ejection (CME) showed some interesting features.
Figure underneath shows the outlook of NOAA 1520 on the day of the flare, as imaged by the SDO-instruments (http://sdo.gsfc.nasa.gov/ ). The top 4 images are taken at 16:30UT, the third pair at 16:45UT (peak), and the bottom pair at 18:55UT. A movie showing the evolution of the event in H-alpha and EUV can be found at http://www.youtube.com/watch?v=CwQFedmo9t4
The Humain radio-telescope (http://sidc.oma.be/humain/index.php ) was also monitoring the Sun at the onset of the flare. The figure underneath shows the evolution of the x-ray flux from 15:15UT till 19:15UT. Below this graph is the radiospectrogram from the Humain radio-telescope for the same period. It shows two features.
The second feature is the bright radio emission continuum that can be seen starting around 17:45UT and lasting for several hours. This is a type IV radio burst and it often accompanies a type II radio burst. Type IV bursts are believed to be generated by the emission of electrons trapped in post-flare loops (see above). Sometimes, also a frequency drift is observed which in turn is linked with the formation of the loops at successively higher altitudes.
The Advanced Composition Explorer (ACE - http://www.swpc.noaa.gov/ace/MAG_SWEPAM_3d.html ) continuously measures the solar wind at 1.5 million km in front of the Earth. As such, it recorded the arrival of the shock preceding the CME on 14 July at 17:28UT.
As the moderately strong magnetic field was oriented southward, Earth suffered from a major geomagnetic storm. This was recorded by the Dourbes Geomagnetic Observatorium (http://gpsweather.meteo.be/geomagnetism/ground_K_dourbes ). The storm was not strong enough to create aurora visible from Belgium. Nonetheless, polar lights were seen as far south as Wales and The Netherlands (low above the horizon).
Solar activity was dominated in the beginning of the period by NOAA 1515, which was then already on the west limb. Soon however, it was the conglomerate of NOAA 1519, 1521 and especially 1520 determining the solar activity, producing several minor M-flares. On Thursday July 12, NOAA 1520 produced an X1.4 flare. The associated CME arrived on July 14th evening.
Proton levels were high in the beginning of the week in the aftermath of the X-flare of the previous period. A new injection of particles was triggered by the X1.4 flare of July 12, the proton flux levels remained above the event threshold until Sunday July 15th.
Departing sunspot group NOAA 1515 (right) and freshly new NOAA 1520 (left) can be seen together on this image made by the White Light telescope of the Uccle Solar Equatorial Table.

Solar Activity
This week, the Sun's activity level was alternating between *moderate* and *low*, with a *high* on Thursday (X1.4 flare). All higher level activity originated from the adjacent active regions NOAA 1520 and NOAA 1521.
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://p2web.oma.be/ssa. This page also lists the recorded flaring events.
At the beginning of the week, the highly active and complex sunspot region NOAA 1515 crossed the West limb producing a series of spectacular eruptions.
A movie, spanning 1 week of activity on the west limb centered around July 9th, mainly generated by NOAA 1515, can be found here: http://proba2.oma.be/swap/data/mpg/movies/campaign_movies/20120705_20120712_SWAP_HV.mp4. The movie was generated with HelioViewer, using (colored) SWAP images.
For comparison purposes, the same SWAP movie was generated with the addition of the SDO AIA image sequence (see here: http://proba2.oma.be/swap/data/mpg/movies/campaign_movies/20120705-20120712_AIA_171_SWAP_174-hq.mp4), thereby showing the differences in the field of view (FOV) of both instruments, and revealing the usefulness of the additional FOV range of SWAP.
One illustrative frame of this ‘composite’ movie is shown below:
SWAP Image - X1.4 flare on Thursday 12/07; at 16:37
The solar wind speed was moderate in the first half of the period (~500 km/s) but periods of southward oriented magnetic field resulted in intermittent episodes of (NOAA estimated) Kp=5 on July 9. After that geomagnetic activity decreased to Kp=1 from July 12 evening till July 14 evening when the CME from the X1.4 flare arrived and produced 36 hours of Kp=5 or 6.

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 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

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.

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.
