The best of ... 2011!

A compilation of the most memorable space weather moments of 2011 can be found underneath. Using the fantastic (J)Helioviewer software, a ***MOVIE*** was created containing one or more clips of each event.

The Sun in August 2011

Solar Activity

The Sun is shifting to an even higher activity level compared to the previous month. The higher values of the International Sunspot Number and the 10cm flux translated into a series of events: a sequel of Earth-directed CME's and flares, the up to now strongest flare of the current cycle and a proton event.

A spectacular solar plasma eruption

On June 07, 2011, there was a spectacular plasma eruption on the Sun. The shock ahead of the plasma cloud skimmed Earth on June 09, 20:00UT. We give a chronological order of how the Space Weather Forecast Centre of Belgium handled the event.

The best of ... 2010!

Looking back at the Seventh European Space Weather Week

European space weather is quickly growing in professionalism and maturity. This has been particarly noticeable at the annual European Space Weather Week, ESWW. Whereas in the past years we still had many wooly discussions of the popular kind, these days we discuss hard core developments, services and new insights. Something is clearly changing.

The 01 August 2010 event - Fully screened

On Aug 01, a series of solar events gave rise to a combination of Earth-directed halo CME's. We screen the event based on SDO and STEREO-Ahead movies, and ACE data.

What is peculiar is the fact that the accompagnied flare was only of a moderate class. It was a combination of different events in a fast sequence. In a way of speaking, all the energies involved in each process added to each other and resulted in a final energetic impact on Earth.

SWAP & LYRA data release - PROBA2 Guest Investigator Program

The ESA micro-satellite PROBA2 was launched last November with two solar instruments onboard: SWAP, an EUV imager, and LYRA, a UV radiometer. SWAP and LYRA have an open data policy. We are happy to announce the beta data release of the science data products.
We also announce the open call for the PROBA2 Guest Investigator Program to promote & fund SWAP and LYRA data analysis by external scientists (submission deadline June 10!).

For the time being, we have online the following FITS files in YYYY/MM/DD directories:

PROBA2 observes a solar eruption that touched Earth

On April 03, 2010, the SIDC sent out a PRESTO message alerting about the halo CME heading for Earth. PROBA2 witnesses the radiation flare associated with the plasma eruption.

The best of ... 2009!

A compilation of the most memorable space weather moments of 2009 can be found underneath. Using the fantastic (J)Helioviewer software, a ***MOVIE*** was created containing one or more clips of each event. Usually, images obtained by SOHO and the STEREO spacecraft were used.
