# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A fast forward shock was detected in the solar wind ACE data around 08:47 UTC on
March 3. The interplanetary magnetic field increased from 2 nT to 5 nT and the solar
wind speed jumped from 280 km/s to 330 km/s. The solar wind density at the shock
increased from 6/cm3 to 16/cm3, and the temperature jumped from about 1.2e4 K to
5.5e5 K. The shock is possibly related to an expected flank ICME arrival related to
the westward partial halo CME first detected in LASCO/C2 data around 17:48 UTC on
February 28. Geomagnetic conditions are expected to be disturbed with unsettled to
active conditions possible depending on the Bz.

# FAST WARNING 'PRESTO' MESSAGE  from the SIDC (RWC-Belgium)         #
#--------------------------------------------------------------------#
A moderate geomagnetic storm was observed globally as the NOAA planetary Kp index
reached 6- between 18:00 UTC and 21:00 UTC today. The storm is possibly associated to
the expected ICME arrival, which is related to the westward partial halo CME first
detected in LASCO/C2 data around 17:48 UTC on February 28. Locally, minor storm
(K-Bel = 5) conditions were observed over Belgium. Further active to moderate
geomagnetic storm conditions may be expected in the next 24 hours.
