SIDC SOLAR BULLETIN 07 Jun 2011, 1242UT
SIDC FORECAST (valid from 1230UT, 07 Jun 2011 until 09 Jun 2011)
SOLAR FLARES  : Quiet conditions (<50% probability of C-class flares)
GEOMAGNETISM  : Minor geomagnetic storm expected (A>=30 or K=5)
SOLAR PROTONS : Proton event in progress (>10 MeV)
PREDICTIONS FOR 07 Jun 2011  10CM FLUX: 098 / AP: 002
PREDICTIONS FOR 08 Jun 2011  10CM FLUX: 098 / AP: 003
PREDICTIONS FOR 09 Jun 2011  10CM FLUX: 098 / AP: 026
COMMENT: An M2.5 flare peaked at 06:30 UT, June 7, 2011. The active
region 1226 is located in the southern hemisphere at the west side of
the visible solar disk. The magnetic configuration of the active region
did not change however dramatically in magnetograms. Magnetograms show
the strength of the line-of-sight surface magnetic field. The flare - a
flash of radiation -as associated with a plasma eruption. SDO/AIA 304
shows the impressive plasma eruption. The plasma cloud is already
visible in SOHO/LASCO and STEREO A-B/COR images. A first estimate gives
a speed over slightly more then 1000 km/s. The cloud seems to have a
large extend and might cause geomagnetic disturbances arriving at Earth
in 2 days. The proton levels went up immediately. >=10MeV and >=50MeV
curve passed the thresshold. This proton event is flare-driven.
