Huge filament eruption in the evening of Thursday 26th of July

A solar prominence/filament, 'sitting' on the North-East limb, erupted on Thu 24th, around 20:45.

 

An eruption on 23rd of July, originating behind West limb - UPDATE: Might have generated one of the fastest CME's ever recorded

 

UPDATE!!!! 25/07/2012

This eruption may have generated the fastest CME ever recorded... To be followed up!

======

This morning, on 23rd of July, at 02:15, a solar eruption could be witnessed, expanding from the West limb. This eruption likely originated from AR11520 which disappeared around the west limb a few days ago.

AR 11520 flares from behind the limb - 20/07/2012

Yesterday early morning, AR 11520, having rotated behind the west limb, erupted and released an M7.7 flare.

 

The first picture shows the eruption and its extent.

NOAA 1515 takes the center stage

NOAA 1515 appeared at the southeastern solar limb on June 27th. With a maximum sunspot area of only about 5 times the total surface of the Earth, it certainly did not become the biggest sunspot group so far this solar cycle.
Nonetheless, the group was quite complex and showed interesting dynamics. For example, the images underneath taken by SDO/HMI ( http://sdo.gsfc.nasa.gov/ ) on 1 and 2 July show the splitting of the main spot in less than 24 hours! Cytokinesis of solar proportions!

PROBA2's Space-Based View of an Annular Solar Eclipse

On Monday, May 21, the shadow of the Moon swept over the Earth, treating observers in North America and East Asia to an annular eclipse. Though it was not visible in Belgium, a pair of Belgian instruments on the PROBA2 had a spectacular view of the eclipse from orbit.

Third Call for PROBA2 Guest Investigators is Open

After two very successful rounds of GI visits, the PROBA2 team has opened a new call for Guest Investigators to visit the PROBA2 Science Center between September 2012 and June 2013.

Complete details about the GI program and application process are available here.

Happy Birthday PROBA2

At 01:50UT, 2 November 2009, SMOS and PROBA2 lifted off on the rockot vehicle from Plesetsk. Since then, SWAP, LYRA, DSLP and DPMU provide a continuous stream of solar and in-situ data towards the Space Weather and Solar Physics communities.
