Solar filaments are clouds of ionized gas above the solar surface squeezed between magnetic regions of opposite polarity. Being cooler and denser than the plasma underneath and their surroundings, they appear as dark lines when seen on the solar disk using special filters. The image below shows such a filament (USET/H-alpha, left - http://sidc.be/uset/ ): the cloud blocks the solar H-alpha radiation leaving a shadow-view of the filament. Its silhouette was added in blue to the magnetogram on the right, clearly marking the borderline between negative (black) and positive (white) magnetic polarities (SDO/HMI, right - http://sdo.gsfc.nasa.gov/ ).
So, when early August a long filament appeared from behind the Sun's southeastern solar limb, it immediately grabbed the attention of the solar observers. The figure underneath shows the Sun on 5 August 2012 at 09:00UT. On the left is a H-alpha view through the USET-telescope, overlaid with a transparent SDO/HMI image (photosphere) showing the location of the filament outside the sunspot regions. The image on the right is made by PROBA2 (http://proba2.oma.be/ ) and shows the same filament as a thin, dark line snaking its way through the much hotter corona.
During the afternoon of August 6, first the northern half erupted, restoring itself in the next few hours. Later that day, it was followed by the eruption of the southern part of the filament, which would also restore itself but needing a lot more time to do so. Then, on August 8, the northern part was permanently ejected. All three events were accompanied by weak and slow-moving coronal mass ejections that did not trigger geomagnetic disturbances.
The remaining half of the filament started its 2 weeks solar backside transit on August 14, leaving solar observers wondering if they have to prepare themselves for a sequel to this die-hard solar filament. Coming soon to a telescope near you!
Solar activity was moderate for most of the week with only C-class flares from August 13 till August 17, taking place in active regions NOAA 1542 and 1543. From August 17 till August 19, 7 M-flares (medium class) occurred as active region NOAA 1548 began its transit on the East limb. The strongest event was a M5.5 flare, which happened on August 18, 01:02 UT (peak time). Underneath images made by the Solar Dynamics Observatory (SDO - http://sdo.gsfc.nasa.gov/ ) clearly show that this flare took place while the sunspot region NOAA 1548 was still behind the Sun's limb.

Solar Activity
Early this week, the Sun's activity level was *Low*, until AR 11548 was closing in from behind the east limb. *Moderate* activity was generated by this AR with several M flares on Friday and Saturday (see table above). On Sunday, when the AR had rounded the limb, the activity went back to *Low*.
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.
Most of the M flares were occurring behind the east limb on Friday and Saturday and so there was only limited viewing available.
However, another couple of interesting phenomena occurred on Monday 13th as well as around midnight on the 15th and 16th.

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
2012 in Bandung Indonesia.

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.

Living With a Star
's Solar Dynamics Observatory
invites you to its 2013 Science Workshop to be held March 3-8, 2013
at the Hyatt Regency Chesapeake Bay in Cambridge, MD
(http://chesapeakebay.hyatt.com/). The workshop is a follow-on to
the 'Many Spectra of Solar Activity' workshop held May 1-5, 2011 in
Squaw Valley, CA.
Scientific sessions will feature a broad spectrum of science
topics fundamental to SDO's science investigations:
Atmospheric Imaging Assembly (AIA), EUV Variability Experiment
(EVE), and Helioseismic and Magnetic Imager (HMI), as well as the
overlap between SDO and other scientific missions and
activities.

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.

Solar cycle 24 has opened a new era in solar radio physics as we
now have instruments that can probe solar processes from
sub-millimeter to kilometer waves. ALMA and LOFAR are entering
full-operation state and observations of the Sun will be made in
the near future.
At the same time extensive use is being made of radio
spectrometers in space, STEREO
/WAVES and Wind
-WAVES, and existing and upgraded
ground-based instruments like Nobeyama Radioheliograph, Nancay
Radioheliograph, Ratan, SSRT, and many others. These instruments
provide data that enable studies of both energetic particles and
thermal plasma
, enhancing our knowledge of solar
eruptions and acceleration and propagation of particles, all
through the solar chromosphere
and corona and into interplanetary
space.
The CESRA 2013 Workshop will highlight these new observational
capabilities and discuss the theoretical issues connected to solar
radio emission and interplanetary radio physics.
