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.
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!
The 2012 Venus transit of the Sun was only visible for a short period in Belgium however it was recorded from beginning to end by a Belgian instrument onboard the satellite PROBA2.
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.
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.
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.
The PROBA2 team is now producing a new data product: deep-exposure SWAP movies that cover an entire Carrington rotation. These movies reveal the dynamics of large-scale coronal structures that typically evolve on very long timescales. Because of SWAP’s unique 54-arcmin field-of-view, these movies reveal many features never before seen in the Extreme-Ultraviolet.
