SIDC SOLAR BULLETIN 09 May 2005, 1234UT
SIDC FORECAST (valid from 1230UT, 09 May 2005 until 11 May 2005)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Quiet (A<20 and K<4)
SOLAR PROTONS : Warning condition
PREDICTIONS FOR 09 May 2005  10CM FLUX: 100 / AP: 017
PREDICTIONS FOR 10 May 2005  10CM FLUX: 101 / AP: 019
PREDICTIONS FOR 11 May 2005  10CM FLUX: 102 / AP: 010
COMMENT: Flaring activity is concentrated around the center of the disk
in sunspot group Catania 60 (NOAA 0758). At the time of writing this
report, it is producing flaring activity. We expect more activity from
this region. The geomagnetic storm which occurred yesterday (CME
arrival) has come to an end. However, the solar wind speed is still
elevated (600 km/s), but the IMF turned northward this morning which
reduces the geoeffectivity mostly. A northern coronal hole is expected
to produce geomagnetic active intervals late today and tomorrow as it
did during its previous solar rotation. So for the next 24 hours quiet
geomagnetic conditions are expected with active intervals. More activity
from NOAA 0758 can lead to more geomagnetic activity later this week.
