# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A halo coronal mass ejection (CME) was observed in LASCO/C2 coronagraph
data starting at 21:36 UTC on February 02. Currently available EUV
observations show no clear on-disk signatures of this CME, suggesting that
its source region is likely on the backside of the Sun as seen from Earth.
Therefore, no impact on solar wind conditions near Earth is expected.
