The GNSS research group of the Solar-Terrestrial Centre of Excellence measured ionospheric disturbances on Jan 22 which impact the communication and satellite navigation at that moment.
On Jan 22, a plasma cloud that travelled from the Sun to the Earth, bumped into the Earth magnetosphere. The plasma was ejected on the Sun on Jan 18-19. The deformation of the Earth magnetic shield was strong enough to cause changes in the ionosphere, a layer of our atmosphere. These changes can disturb radio communication and satellite navigation.
In particular, the Global Navigation Satellite System or GNSS research group of the Solar-Terrestrial Centre of excellence noticed that the Total Electron Content, TEC changed considerably due to the arrival of the cloud. The American GPS and the European Galileo make part of GNSS. The TEC is a measure for the total number of electrons present in a cylindrical volume of 1m2 cross section, straight through the ionosphere. The TEC determines how signals pass through the ionosphere. On Jan 22, the communication and satellite navigation was vulnerable due to the arrival of a solar plasma cloud.
On Jan 23, a relative strong flare occurred, a plasma cloud was ejected and not long after these events, a stream of protons passed several satellites and finally hit the Earth. The solar wind speed measurements done by the satellite ACE were interrupted because of this proton storm as you can see in the top panel of the picture. The bulk of the plasma cloud did not hit the Earth, it was only a glancing blow. The GNSS research group did not notice any disturbances at the time of arrival. On Jan 24, the communication and satellite navigation was not disturbed because of to the glancing blow of the Jan 23 solar plasma cloud.
The ionosphere is a peel around the Earth making part of our atmosphere. The ionosphere is the key layer for communication. For satellite navigation, a signal passes through the ionosphere. For other purposes like long distance radio communication, the ionosphere is used as a mirror to reflect radio signals such that these signals can bounce back to a receiver. It's clear that if the ionosphere is disturbed and changes features, navigation and radio communication can be in trouble. Space Weather can alter the features of the ionosphere.
The ionosphere is formed by the UV and X-ray solar radiation - the sort of radiation that travels with the speed of light and that doesn't need a medium to propagate. If the intensity and the strength of that radiation suddenly changes, the ionosphere and its properties also change. A sudden and intense brightning on the sun, a flare, can introduce ionospheric irregularities on the day side of the Earth.
When a plasma cloud hits the Earth's magnetosphere, our magnetic shield, it causes a geomagnetic storm. Such a storm on its turn can also drive the ionosphere away from its more regular state. A geomagnetic storm can pass along the day side, but also on the night side. A geomagnetic storm is generally linked with latitude: closer to a pole of the Earth, the stronger a geomagnetic storm can be.
For comparison: the magnetosphere extends up to 20 - 25 Earth radii (= 6353 km) on the day-side, i.e. around 130 000 - 160 000 km, while the atmosphere is a layer of 100 km.

* LYRA curves for the X1.7 event of Friday 27/01/2012:
Solar activity was dominated by the flaring activity of NOAA AR 1402, which produced a M8.7 flare on Jan. 23 (0359 UT peak time) accompanied by a fast halo CME (1400 km/s as measured using COR2 A coronagraph) and a proton event (10 and 50 MeV protons), which ended on Jan. 27.
The >10 MeV proton flux reached quite a high value of 6300 pfu on Jan. 24 at about 1530 UT, shortly after the arrival of the shock linked to the halo CME at Earth.
While close to the west limb, AR 1402 produced an X1.7 class flare on Jan. 27, peaking at 1837 UT. It was linked again to a fast halo CME (1900 km/s on COR2 A) and a new proton event from 10 to 100 MeV, although the maximum of the 10 MeV flux was below 1000 pfu.
Geomagnetic activity reached minor storm levels at planetary level on Jan. 24 due to the arrival of the shock, linked to the halo CME of Jan. 23 around 14:30 UT. Unsettled to active periods were observed for nearly 24 hours. Apart from a brief period of active conditions on Jan. 23, which was the tail of a previous minor storm, the rest of the week was rather quiet.

This meeting will combine a historic overview on (Flemish) scientific achievements made in plasma-astrophysics, together with a state-of-the-art, international viewpoint on modern algorithmic developments for space plasmas. The meeting intentionally coincides with celebrating the 20 year existence of the Centre for Plasma Astrophysics (Department of Mathematics, K.U.Leuven), along with the upcoming emeritus status of its founder, Prof. Marcel Goossens. At the same time, the first annual progress meeting of the FP7-project SWIFF (space weather integrated forecasting framework), coordinated by Prof. Giovanni Lapenta, will provide the most updated account of modern, algorithmic-computationally driven research efforts in space plasma modeling. The weeklong event will serve to survey acquired knowledge, identify modern challenges barely researched by theoretical approaches, and stimulate new collaborations on both historic as well as contemporary open questions.
The meeting objective is to, on the one hand, present the space weather integrated forecasting framework (SWIFF) progress to the wider scientific community, and provide an opportunity for cross-fertilization of related international efforts on multi-physics modeling. As ongoing FP7 project, its annual meeting allows to present the first achieved milestones to scientific peers. Part of the programme will be filled in through an open call for also project-external contributions, and the remainder will concentrate on the achievements in the various work packages. The final two days shift the objective from future developments to acquired knowledge and achievements made as a result of 20 years of Centre for Plasma Astrophysics (K.U.Leuven) initiated research, ending with an international tribute to its founder. In the last two days, we foresee a programme of invited international speakers whose research has benefitted from K.U.Leuven collaborations, along with a contemporary contribution from current staff members.

Each year, the International Space University (ISU) organizes a three day symposium addressing a topical theme from an interdisciplinary and international perspective. These symposia attract an audience of around 200 members of the space sector from agencies, industry and academia worldwide.
Our next annual symposium, the sixteenth in a series, will address the risks faced by spacecraft and crew due to various natural and human generated threats. Looking beyond the current situation we ask what can be done to mitigate the threats in order to assure long-term sustainability of space activities particularly through increased co-operation between nations.
The scope of the Symposium will be in line with the main objective of the UN COPUOS Working Group on the subject established in early 2010, that is, “to examine and propose measures to ensure the safe and sustainable use of outer space for peaceful purposes, for the benefit of all countries”.

An overarching theme of the meeting is to cover how different regions in the solar atmosphere are coupled, with a particular focus on the chromosphere, the region where most of the non-thermal energy in the solar atmosphere is deposited. The meeting will focus on quiescence, i.e., the non-flaring, non-eruptive state of the atmosphere in coronal holes, quiet Sun and active regions.
The major goals of this meeting are:
* Provide an overview of recent insights in how different regions in the solar atmosphere are coupled and energized with a focus on how magnetic flux, mass and energy are transported through the atmosphere. This will be done by confronting recent advanced numerical models with state-of-the-art high resolution observations.
* Provide the community with an overview of outstanding challenges, such as the heating of the chromosphere, its connection to the corona, the role and interpretation of chromospheric magnetism in revealing the connectivity and energy deposition in the low solar atmosphere, and the relative role of waves and braiding in the heating of coronal plasma.
* Prepare the community to fully exploit the novel diagnostic capabilities that will be provided by future missions such as the Interface Region Imaging Spectrograph (IRIS) small explorer, due for launch in late 2012, ESA's Solar Orbiter, or Japan's Solar C mission. This will be done in part by providing tutorial and discussion sessions on optically thick chromospheric diagnostics (including spectropolarimetry) which are a major part of the diagnostic capabilities of both missions, and in part by illustrations of how detailed comparisons between synthetic observables from numerical models and observations lead to physical insights.

Impact of solar and geomagnetic variabilities on the Earth's lower,middle
and upper atmospheres (Thierry Dudok de Wit, Jean Lilensten, F.-J. Lübken, M. Kaufmann and P. Preusse)
This interdisciplinary session focuses on the multiple impacts of solar activity on climate variability. The session will address both forcing mechanisms such as solar spectral irradiance, geomagnetic perturbations and galactic cosmic rays, and the response of the upper, middle and lower atmosphere. Special attention will be payed to the solar flares and
geomagnetic storms as well as to the role of the long-term trends of the solar activity, in particular, in global climate changes and modern global warming. Papers involving the physical processes in the ionosphere and stratosphere will be welcome in the first place. The objective is to go beyond correlation analyses and gain a better quantitative understanding of the different contributions of solar variability to the terrestrial environment.

As the impact of space weather and climate on daily life is becoming more important, it is timely to discuss the latest reseach on the solar origin of these phenomena. Recent advances in helioseismology have demonstrated that subsurface dynamics are closely associated with aspects of solar activity from the long-term timing of the solar cycle to the short-term eruption of solar flares. The advent of synoptic vector magnetic field measurements is opening up a new path for research on active regions, flares and CME's. Coronal magnetic field measurements should become available in the next 5-10 years, supplying another physical constrain on space weather events.

Helioseismology and asteroseismology are the only means to investigate the interior of the Sun and stars. They are crucial for understanding the structure and evolution of stars, which produce all chemical elements in the universe heavier than helium, and which host and influence planets which may carry life. Understanding the physics of the Sun's interior is essential for understanding the solar dynamo and consequently for predicting solar magnetic activity, which has a severe impact on the operation of space missions. Understanding the interior of the stars is essential for understanding those astronomical objects that host and influence planets. With the suite of the latest instruments and missions, e.g. BiSON, GONG, SOHO, SDO, Hinode and Picard for solar exploration and MOST, CoRoT, Kepler, BRITE, SONG for stellar and exoplanetary research, the precision on the seismically determined quantities, e.g. flows in the solar interior or the ages and radii of stars will be greatly improved. This will allow creating new knowledge in solar physics and astrophysics and therefore makes the proposed conference particularly timely.

The purpose of this workshop is to foster the development of tools to interpret current and future measurements of coronal magnetic fields in order to improve our understanding of the Sun and the sources of Space Weather. This is motivated by the anticipated rapid growth over the next decade in our remote sensing capabilities of the coronal plasma. These new capabilities can only be exploited with improvements in our ability to model the polarized radiative transfer through the coronal plasma and by coupling information on the coronal magnetic field and plasma conditions with models extending to the near Earth environment.
This workshop will include a wide variety of subjects including, but not limited to, instrumentation, the interpretation of polarimetric signals in EUV and UV emission lines, techniques to mitigate the effects of line-of-sight integration effects of the optically thin corona such as tomographic inversions and forward modeling, models of the polarized radiative transfer at radio wavelengths, extrapolation and MHD modeling of coronal magnetic fields, as well as discussions on how to move forward with coupling these inferences of the coronal plasma with models of heliospheric structure and Space Weather prediction.

The Space Weather Integrated Forecasting Framework network (http://www.swiff.eu) organizes in June 2012 the “First European School on Fundamental processes in space weather, a challenge in numerical modeling”. The School will focus on the theoretical study of Space plasmas, in particular on those systems where a continuous energy injection flow leads to a self-consistent coupling of the large scale, low frequency motions with the small scale, high frequency fluctuations including kinetic effects. Progress in this field heavily relies on numerical simulations that, as a matter of fact, are nowadays more similar to laboratory experiments than to theoretical exercises. This is true in terms of planning efforts in the preparatory phase, of manpower required, of data analysis and cost. The understanding of these processes represents a fundamental step for the future of Space Weather models.

During the last thirty years there has been steady progress in our understanding of the influence that space weather has on the state of human health both in Space and at Earth. This development is mainly based on research conducted on humans onboard space stations and spacecrafts, as well as on ground based observations and experimental studies simulating conditions in space. This interdisciplinary field of research requires a wide exchange of expertise in various topics. Only with a global approach it will be possible to establish a mutual understanding, in regard to defining the current state of this research problem as well as identifying what should be pursued in future research activities.

We announce the 'Second Remote Sensing of the Inner Heliosphere Workshop' to be hosted by Aberystwyth University and held in Aberystwyth, Wales, UK, 06-10 June 2011. 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 issues, establish closer working relations, and devise the best ways to move the field forward. In addition, the science learned from remote-sensing observations is key to improving our capabilities of space weather forecasting. The workshop also 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 sub-communities, ways in which we model the inner heliosphere looking at the advantages and disadvantages of the available modelling, updates on present and future remote-sensing capabilities - including those on the STEREO/SDO/Solar Orbiter/Solar Probe+ Missions, and progress on use of the LOw Frequency ARray (LOFAR) and Murchison Widefield Array (MWA) radio arrays - pathfinders for the Square Kilometre Array (SKA) - linking remote-sensing observations of the inner heliosphere with those closer-in to the Sun as well as with in-situ measurements, 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.

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.
