:Product: 0402RSGA.txt :Issued: 2012 Apr 02 2200 UTC # Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Weather Prediction Center and the U.S. Air Force. # Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 093 Issued at 2200Z on 02 Apr 2012 IA. Analysis of Solar Active Regions and Activity from 01/2100Z to 02/2100Z: Solar activity has been very low for the past 24 hours. Region 1451 (N17E25) produced a B7 event at 02/0234Z. New Regions 1452 (N18E47) and 1453 (S17E01) were numbered today. A weak Earth-directed CME, associated with a filament eruption near N26E14, became visible on LASCO C2 imagery at 02/0224Z. IB. Solar Activity Forecast: Solar activity is expected to be very low with a chance for C-class activity for the next three days (03-05 April). IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic field was quiet to unsettled during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet on day one (03 April). Quiet to unsettled conditions are expected on days two and three (04-05 April) due to a coronal hole high speed stream becoming geoeffective early on 04 April followed the next day by the arrival of the weak CME associated with this mornings filament eruption.
