| Report of Solar-Geophysical Activity Issued: 2007 Mar 01 2200 UTC Prepared jointly by the U.S. Dept. of Commerce, NOAA, # Space Environment Center and the U.S. Air Force.
Joint USAF/NOAA Report of Solar and Geophysical Activity SDF Number 060 Issued at 2200Z on 01 Mar 2007 IA. Analysis of Solar Active Regions and Activity from 28/2100Z to 01/2100Z: Solar activity was very low. There were no flares during the past 24 hours. IB. Solar Activity Forecast: Solar activity is expected to be very low. IIA. Geophysical Activity Summary 28/2100Z to 01/2100Z: The geomagnetic field ranged from active to quiet levels. Solar wind speed remained elevated due to a coronal hole stream, but gradually declined during the past 24 hours. The greater than 2 MeV electron flux reached high levels during the past 24 hours. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet for the next three days. III. Event Probabilities 02 Mar-04 Mar Class M 01/01/01 Class X 01/01/01 Proton 01/01/01 PCAF Green IV.
