SIDC SOLAR BULLETIN 17 Mar 2010, 1253UT
SIDC FORECAST (valid from 1230UT, 17 Mar 2010 until 19 Mar 2010)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 17 Mar 2010  10CM FLUX: 084 / AP: 011
PREDICTIONS FOR 18 Mar 2010  10CM FLUX: 083 / AP: 008
PREDICTIONS FOR 19 Mar 2010  10CM FLUX: 082 / AP: 004
COMMENT: The main active region on the Sun (NOAA11054, Catania #52) is
now declining and did not produce any flare over the past 48 hours. We
thus expect low solar activity. The solar wind speed increased over the
last 24 hours, now reaching 500 km/s. It is unclear if this is a weak
recurrent fast solar wind stream or a glancing blow of the slow March 14
CME expected to arrive today March 17. In either cases, we only expect
that the current quiet to unsettled geomagnetic conditions may be
temporarily enhanced to active levels over the next 24 hours, before
returning to quiet levels.

TODAY'S ESTIMATED ISN  : 019, BASED ON 12 STATIONS.
