SIDC SOLAR BULLETIN 26 Jan 2007, 1217UT
SIDC FORECAST (valid from 1230UT, 26 Jan 2007 until 28 Jan 2007)
SOLAR FLARES  : Active (M-class flares expected, probability >= 50%)
GEOMAGNETISM  : Active conditions expected (A>=20 or K=4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 26 Jan 2007  10CM FLUX: 082 / AP: 004
PREDICTIONS FOR 27 Jan 2007  10CM FLUX: 084 / AP: 005
PREDICTIONS FOR 28 Jan 2007  10CM FLUX: 086 / AP: 017
COMMENT: The active region right at the east limb (NOAA AR 0933 during
the previous rotation) keeps a potential to produce a C- and even an
M-flare. The CME associated with the C6.3 flare yesterday was a full
halo. However, it was strongly asymmetric with the bulk of material
going towards the east. We thus do not expect any resulting geomagnetic
disturbance. The low-latitude coronal hole in the southern hemisphere
reached the central meridian. We expect the fast flow originating from
this coronal hole to arrive to the Earth on January 28. A geomagnetic
disturbance up to the minor storm level is possible. The Earth is
currently inside the slow solar wind flow, so we do not expect any
significant geomagnetic activity in the coming hours.

TODAY'S ESTIMATED ISN  : 008, BASED ON 04 STATIONS.
