# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A partial halo coronal mass ejection (CME) was observed in LASCO C2 data to
lift off the solar surface from the south-west limb around 18:48 UTC on May
11th. The CME is related to a prominence eruption following low M-class
flaring from behind the west limb. The CME appears back-sided and is
expected to miss the Earth.
