> 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 22 Apr 2005 10CM FLUX: 079 / AP: 020

> PREDICTIONS FOR 24 Apr 2005 10CM FLUX: 079 / AP: 019
> COMMENT: Solar activity continues at the very low levels we have been
> seeing over the past few days. Only a few small spots are visible on the
> solar disk, none harbouring any significant activity. A loop system at
> the east limb indicates the imminent appearance of a new sunspot group,
> but this appears to show little activity. A fairly large but slow CME
> originated from behind the southeast limb.
> Geomagnetic activity has been at quiet level over the past 24 hours. The
> solar wind speed decreased to 500 km/s, but we expect it to increase
> soon due to the transequatorial coronal hole west of the central solar
> meridian. Minor storm conditions may follow.
