> SIDC FORECAST (valid from 1230UT, 10 Apr 2005 until 12 Apr 2005)
> SOLAR FLARES : Eruptive (C-class flares expected, probability >= 50%)
> GEOMAGNETISM : Minor geomagnetic storm expected (A>=30 or K=5)
> SOLAR PROTONS : Quiet
> PREDICTIONS FOR 10 Apr 2005 10CM FLUX: 088 / AP: 011
> PREDICTIONS FOR 11 Apr 2005 10CM FLUX: 087 / AP: 026
> PREDICTIONS FOR 12 Apr 2005 10CM FLUX: 085 / AP: 015
> COMMENT: NOAA AR 0751, Catania sunspot group 52, has produced several
> strong B-flares yesterday and today. A C-flare from this active region
> is possible. A large low-latitude coronal hole is visible in the
> northern hemisphere. We expect the fast flow produced by this coronal
> hole to arrive to the Earth tomorrow. Disturbed geomagnetic conditions
> up to the minor storm level (Kp = 5) are thus possible.
