SIDC SOLAR BULLETIN 10 Mar 2005, 1235UT
SIDC FORECAST (valid from 1230UT, 10 Mar 2005 until 12 Mar 2005)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 10 Mar 2005  10CM FLUX: 105 / AP: 024
PREDICTIONS FOR 11 Mar 2005  10CM FLUX: 110 / AP: 018
PREDICTIONS FOR 12 Mar 2005  10CM FLUX: 115 / AP: 008
COMMENT: Active regions #40 (NOAA742) and #38 (NOAA 741) have been
growing further (both Beta configuration). They may produce C flares and
a possible isolated M flare in the coming days, in particular AR 38/741.
A C8 flare was just produced by this region at 11:40 UT.
The solar wind speed still remains high, at 650-700km/s, with Bz
fluctuating near 0. Late yesterday, Bz stayed sligthly negative for a
few hours, which produced active to minor storm conditions at the Earth
during that period. The geomagnetic field is expected to remain
unsettled to active, as it is now, for one more day, with still a chance
for temporary minor geomagnetic storms at high latitudes. Thereafter, by
March 12, the geomagnetic field should return to quiet conditions, as
the fast wind infuence finally decays.
