SIDC SOLAR BULLETIN 09 Apr 2010, 1141UT
SIDC FORECAST (valid from 1230UT, 09 Apr 2010 until 11 Apr 2010)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Minor geomagnetic storm expected (A>=30 or K=5)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 09 Apr 2010  10CM FLUX: 074 / AP: 012
PREDICTIONS FOR 10 Apr 2010  10CM FLUX: 074 / AP: 022
PREDICTIONS FOR 11 Apr 2010  10CM FLUX: 072 / AP: 043
COMMENT: Solar activity is expected to be very low for the next 48
hours. The long duration B3.7 flare of April 8, peaking at 03:25 UT was
associated with a halo CME. Observations gathered from the STEREO
spacecrafts and SOHO suggest that this CME is Earth-directed. We expect
therefore a possible significant impact on geomagnetic conditions either
on late April 10 (saturday) or more likely on April 11 (sunday). Minor
storm with possibly major storm periods are possible.
