We hope to welcome you at our yearly STCE event! 2. PROBA2 Observations (19 May 2014 - 25 May 2014)
Solar flare activity was low this week, except on Saturday when an M1.3 flare occurred.
In order to view the activity of this week in more detail, we suggest going to the following website fromwhich all the daily (normal and difference) movies can be accessed: http://proba2.oma.be/ssa.
This page also lists the recorded flaring events.
A weekly overview movie can be found here: http://proba2.oma.be/swap/data/mpg/movies/WeeklyReportMovies/WR217_May19_May25/weekly_movie_2014_05_19.mp4 (SWAP week 217).
Details about some of this week's events can be found further below.

Solar activity was mostly at C level during the week of May 19 to 25, 2014. In total, one M flare and23 C flares were observed. There was some sporadic C flaring from NOAA regions 2066, 2071, 2072,2073, and 2068 in the first half of the week. In the second half of the week, AR 2068 released almostall C flares and the M1.3 flare of May 24.

Solar wind speed as observed by ACE was low (between 300 and 350 km/s) until the arrival of a highspeed stream from a southerly coronal hole.
The co-rotating interaction region arrived on May 22. The solar wind speed increased up to about 500km/s on May 23, causing a minor geomagnetic storm in the late UT hours of that day. Geomagnetic 19 May 2014 - 25 May 2014

activity has been quiet (K Dourbes and NOAA Kp less than 4) throughout the rest of the week. The solarwind speed had decreased to about 400 km/s at the end of May 25.

6. Review of ionospheric activity (19 May 2014 - 25 May 2014)
The figure shows the time evolution of the Vertical Total Electron Content (VTEC) (in red) during thelast 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) 19 May 2014 - 25 May 2014

This figure also shows (in grey) the normal ionospheric behaviour expected based on the median VTECfrom the 15 previous days.
The VTEC is expressed in TECu (with TECu=10 16 electrons per square meter) and is directly relatedto 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 60kmto 1000km above the Earth's surface.The ionization process in the ionosphere produces ions and freeelectrons. These electrons perturb the propagation of the GNSS (Global Navigation Satellite System)signals by inducing a so-called ionospheric delay.

STCE workshop on degradation and inter-calibration of instruments observing
in the SXR-EUV range in Brussels, Belgium
Start : 2014-06-10 - End : 2014-06-11The STCE workshop 'Inter-Calibration and Degradation of EUV Instruments' aims at understanding thedifferences observed between the various instruments observing in the SXR-EUV range and at analyzingthe ageing effects that affect their results. It targets imagers as well as spectrometers and photometers.
The workshop will be followed by two days of working sessions (June 12-13) organized by the Solar EUVIrradiance Working Group (also supported by the STCE). These working sessions are in the continuityof similar events organized in 2011, 2012 and 2013, but they are open to new participants and you arewelcome to join if you are interested.

http://www.spaceweather.eu/en/repository/show?id=519 eHEROES - where Space Weather and Communication meet
Raising awareness and get people outside the scientific community involved in space weather becomesmore and more an issue. To cross the borders of our science project eHEROES, we came up with a tidecommunication plan that answers the questions: what, to whom, why, when, how, by whom? The key is tolink the audience and your message in a correct way. Both formal and informal education are on our toollist. This is an invited poster presented at EGU, 2014 in the session Raising and maintaining awareness ofour local space weather: education and public outreach. eHEROES, Environment for Human Explorationand RObotic Experimentation in Space is an FP7 project (n° 284461, www.eheroes.eu).
