:Product: 0506RSGA.txt :Issued: 2012 May 06 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 127 Issued at 2200Z on 06 May 2012 IA. Analysis of Solar Active Regions and Activity from 05/2100Z to 06/2100Z: Solar activity has been at moderate levels for the past 24 hours with three impulsive, low level M-class events observed from Region 1476 (N10E63). The largest event was an M1/1n at 06/1747Z. Region 1476 has rotated further into view and is now classified as a Fhi/beta-gamma sunspot group with an area of around 760 millionths. Three filament eruptions were also observed in the past 24 hours, but none appear to have an earthward directed component. No new regions were numbered today. IB. Solar Activity Forecast: Solar activity is expected to be at low to moderate levels for the next three days (07 - 09 May) as Region 1476 continues to evolve and rotate further onto the visible disk. IIA. Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic field has been at mostly quiet levels for the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (07 - 08 May) due to a solar sector boundary crossing and the possible arrival of a CME, observed lifting off the solar disk on 05 May. A slight increase to quiet to unsettled levels with a chance for an active period is expected on day three (09 May) as a corotating interactive region, in front of a high speed solar wind stream, is expected to arrive here at Earth.
