SIDC SOLAR BULLETIN 09 May 2006, 1321UT
SIDC FORECAST (valid from 1230UT, 09 May 2006 until 11 May 2006)
SOLAR FLARES  : Eruptive (C-class flares expected, probability >= 50%)
GEOMAGNETISM  : Minor geomagnetic storm expected (A>=30 or K=5)
SOLAR PROTONS : Quiet
PREDICTIONS FOR 09 May 2006  10CM FLUX: 085 / AP: 006
PREDICTIONS FOR 10 May 2006  10CM FLUX: 084 / AP: 020
PREDICTIONS FOR 11 May 2006  10CM FLUX: 083 / AP: 022
COMMENT: Active region Catania#37 (NOAA0882) has grown over the last
24h and may produce C flares in the next 1 or 2 days, raising a bit the
solar activity. The high-speed solar wind stream has decayed further (v=
430km/s, B= 5nT) and consequently, the geomagnetic field has remained
quiet. We expect those quiet conditions to continue for about 24 hours.
Then, a recurrent fast stream will initiate a new geomagnetic storm
(Kp=5 or 6 based on previous recurrences).

TODAY'S ESTIMATED ISN  : 026, BASED ON 03 STATIONS.
