Solar Activity was at moderate levels. Region 9802 (S15W56) produced an M1.3/Sf flare at 04/2330 UTC. Region 9802 continues to show gradual decay but remains a magnetically complex Beta-gamma-delta region. Region 9816 (S12W46) growth continues but at a slower rate than yesterday. A large positive polarity coronal hole near central latitude is currently rotating into a geo-effective position. Solar wind speed has increased to 550 km/sec at the time of forecast issue. Three new regions were numbered today: Region 9817 (S07E23), Region 9818 (N06E54), and Region 9819 (S29E68).

Solar activity is expected to be low to moderate. Region 9802 and has the potential for M-class events.

The geomagnetic field was at unsettled to active levels with one 3 hour period of quiet conditions.

The geomagnetic field is expected to be at unsettled to active levels due to coronal hole effects. Quiet to unsettled conditions is expected to return by day three of the forecast period.
