SIDC URSIGRAM 20127
SIDC SOLAR BULLETIN 27 Jan 2012, 1215UT
SIDC FORECAST (valid from 1230UT, 27 Jan 2012 until 29 Jan 2012)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 27 Jan 2012  10CM FLUX: 122 / AP: 017
PREDICTIONS FOR 28 Jan 2012  10CM FLUX: 123 / AP: 012
PREDICTIONS FOR 29 Jan 2012  10CM FLUX: 126 / AP: 007
COMMENT: Solar activity is likely to stay at eruptive levels for the
next 24 hours with risks of C flares from NOAA AR 1402. The proton event
in progress since Jan. 23 just passed today below the 10 pfu threshold
(for > 10 MeV protons) and is therefore official over. Geomagnetic
activity is expected to be active within the next 24 hours, due to a
coronal hole becoming geoeffective. Current solar wind conditions
measured by ACE are quiet.



TODAY'S ESTIMATED ISN  : 044, BASED ON 15 STATIONS.
