FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium) 2015 Apr 28 20:31:00

SDO/AIA and H-alpha GONG images indicate the eruption of the extended filament, which was stretching from S05E10 to N40E80, starting around 11:00 UT (April 28). The eruption was triggered by the eruption of a filament that was located south of this large one. The eruption was followed by a Hyder flare. Due to the location of the eruption, a halo CME is to be expected. The first coronagraphic data of SOHO/LASCO do indicate the occurrence of a CME, but more images are required for further analysis of its characteristics and estimate the effects on Earth's environment.
