SIDC SOLAR BULLETIN 10 Feb 2010, 1224UT
SIDC FORECAST (valid from 1230UT, 10 Feb 2010 until 12 Feb 2010)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 10 Feb 2010  10CM FLUX: 091 / AP: 001
PREDICTIONS FOR 11 Feb 2010  10CM FLUX: 091 / AP: 007
PREDICTIONS FOR 12 Feb 2010  10CM FLUX: 091 / AP: 005
COMMENT: The rotation of the Bz component of the interplanetary
magnetic field from negative to positive values on Feb 09. Several solar
wind parameters made a sudden jump just before this rotation. These
phenomena are can be linked with the arrival of the CME associated with
the M-flare of Feb 07. The influence was limited: geomagnetic conditions
were quiet: the magnetic field was not intense. The CME associated with
an M-flare of Feb 08 was not detected by CACTus as an (partial) halo CME.
The total X-ray flux decreased. The probability for M-flares is below
50%. C-flares are still probable.

TODAY'S ESTIMATED ISN  : 039, BASED ON 08 STATIONS.
