:Product: 0123RSGA.txt :Issued: 2008 Jan 23 2203 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 023 Issued at 2200Z on 23 Jan 2008 IA. Analysis of Solar Active Regions and Activity from 22/2100Z to 23/2100Z: Solar activity was at very low levels. The visible solar disk remained spotless. A slow-moving coronal mass ejection (CME) was seen in LASCO imagery off the southeast limb beginning at 23/0042Z. This event appears to have originated from behind the limb. IB. Solar Activity Forecast: Solar activity is expected to continue at very low levels. IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic field was at quiet levels. The greater than 2 MeV flux at geosynchronous orbit was at high levels again today. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to remain at quiet levels for the next three days (24 - 26 January). III.
