# FAST WARNING ‘PRESTO’ MESSAGE from the SIDC (RWC-Belgium) #
#——————————————————————–#
SoHO/LASCO C2 images show an asymmetric full halo CME from 12:48 UT Nov 24 onwards. STEREO A COR2 Beacon Data clearly shows the event from around 13:24 UT originating from the backside (in relation to Earth) of the Sun. The CME will thus not influence Earth.
