# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A faint partial halo CME was observed to the north-east first seen in
SOHO/LASCO-C2 data from 20:12 UTC March 16. This is possibly associated
with an on-disk eruption and dimming observed in the north east quadrant
from 19:00 UTC in SDO/AIA 193. Analysis is ongoing, but given the assumed
source location and CME width, a glancing blow at Earth may be possible
from March 20.
