# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
The global geomagnetic conditions reached moderate storm levels (NOAA Kp 6)
yesterday between 18:00-21:00 UTC. This is the result of a Coronal Mass
Ejection (CME) arrival yesterday at 12:44 UTC. The geomagnetic conditions
dropped back to active levels (NOAA Kp 4-) today at 00:00 UTC and are
expected to drop further as the effects from the CME wane.
