Welcome to the Solar Influences Data Analysis Center (SIDC), which is the solar physics research department of the Royal Observatory of Belgium. The SIDC includes the World Data Center for the sunspot index and the ISES Regional Warning Center Brussels for space weather forecasting.

FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium) 2015 Apr 26
07:09:07

An asymmetric full halo CME is visible in SoHO/LASCO coronagraph data from
14:48UT onwards in C2 field of view.
The angular width was underestimated by Cactus.
No related on disc activity could be associated, and the event is believed
to be backsided and hence not geoeffective.
