# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
Solar coronal dimming was observed today, on July 04, starting at around 02:12 UTC
and ending around 04:09 UTC. The coronal dimming was located close to the Sunspot
region NOAA AR 3359. A partial halo coronal mass ejection (CME), associated to the
dimming, was first observed in SOHO/LASCO-C2 at around 04:12 UTC on July 04. The CME
is directed to the south-east and the bulk of the CME is not expected to be Earth
directed. However, a glancing blow at Earth is possible. Analysis is ongoing to
estimate the potential impact of the CME and its arrival time.
