# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A relatively long duration C1.3-class flare was observed at  03:19 UT on
March 08. This flare originated from Catania sunspot group 9 (NOAA Active
Region 2734), which was located at about 7 degrees latitude North and 10
degrees longitude West. A coronal dimming was observed to be associated
with this flare, and a coronal mass ejection (CME) was also observed in
SOHO/LASCO-C2 data (no STEREO-COR3 data are available). The projected CME
speed in the plane of the sky was estimated to be in the range of 288 km/s
and 331 km/s by the CACTUS detection tool, and we have evaluated the
corrected speed to be around 440 km/s. The slow speed CME is expected to
reach Earth in about 4 days, on March 12 midday.
