SIDC FORECAST (valid from 1230UT, 25 Jan 2007 until 27 Jan 2007)
SOLAR FLARES  : Active (M-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 25 Jan 2007  10CM FLUX: 081 / AP: 001
PREDICTIONS FOR 26 Jan 2007  10CM FLUX: 083 / AP: 002
PREDICTIONS FOR 27 Jan 2007  10CM FLUX: 085 / AP: 005
COMMENT: An active region currently just behind the East limb (NOAA AR
0933 during the previous rotation) produced two long-duration flares:
B9.0 peaking at 14:52 UT yesterday and C6.3 peaking at 07:12 today. Both
flares are accompanied by wide CMEs, but the source region position
behind the east limb makes their arrival to the Earth unlikely. More C
and even M flares are probable from this active region. The Earth is
inside the slow solar wind flow, so the geomagnetic conditions are
expected to remain quiet in the coming hours. We, however, expect the
arrival of a fast solar wind stream from the low-latitude coronal hole
in the southern hemisphere. Disturbed geomagnetic conditions up to the
minor storm level are possible starting from January 28.

TODAY'S ESTIMATED ISN  : 009, BASED ON 03 STATIONS.
