SIDC URSIGRAM 50123
SIDC SOLAR BULLETIN 23 Jan 2005, 1220UT
SIDC FORECAST (valid from 1230UT, 23 Jan 2005 until 25 Jan 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 23 Jan 2005  10CM FLUX: 098 / AP: 016
PREDICTIONS FOR 24 Jan 2005  10CM FLUX: 090 / AP: 021
PREDICTIONS FOR 25 Jan 2005  10CM FLUX: 089 / AP: 017
COMMENT: Solar wind speed is still at the elevated level of 650 km/s.
The fact that the solar wind speed is not decreasing any more (after the
shockarrival) can be possibly caused by the northern hemispheric coronal
hole. Last night (Jan 22 - Jan 23) we had some active geomagnetic
periods. Up till tomorrow, periods of active conditions can still occur.
Sunspot group 05 (NOAA 720) still produced an M-flare peaking at 01:51
UT, Jan 23. Other active regions now visible on the solar disk are
behaving quiet.
