# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
An M5.5 flare occurred in AR NOAA 2929, with peak at 06:01 UT. As a
consequence, a proton event is ongoing at the Earth (10 MeV protons above
10 pfu). It is associated with a CME, but there are not enough images yet
to provide a good estimation of its parameters. Since the source region is
located almost at the west limb, an effect on the Earth is for the moment
not expected.
