SIDC SOLAR BULLETIN 26 Feb 2005, 1403UT
SIDC FORECAST (valid from 1230UT, 26 Feb 2005 until 28 Feb 2005)
SOLAR FLARES : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 26 Feb 2005 10CM FLUX: 076 / AP: 016
PREDICTIONS FOR 27 Feb 2005 10CM FLUX: 074 / AP: 022
PREDICTIONS FOR 28 Feb 2005 10CM FLUX: 074 / AP: 011
COMMENT: The solar activity is very low and is expected to remain at
very low level. The only noteworthy event was the eruption, on Feb.25
around 02:00UT, of the SE section of the huge filament that crossed the
solar disk over the last week. Given its high latitude, this eruption is
probably not Earth-directed. The solar wind speed is now at 550km/s and
Bz fluctuates strongly around 0. This causes unsettled to active
conditions, which are expected to continue for one day.
