NOAA SEC Report of Solar-Geophysical Activity 3 Dec 2000
:Product: Report of Solar-Geophysical Activity :Issued: 2000 Dec 03 2200 UT # 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 338 Issued at 2200Z on 03 Dec 2000 IA. Analysis of Solar Active Regions and Activity from 02/2100Z to 03/2100Z: Solar activity remained at the low level. Very little eruptive activity occurred, but the disk did experience considerable change from yesterday. Six new regions were numbered. They are: 9250 (S11W80), 9251 (S22W34), 9252 (S02W36), 9253 (S14E11), 9254 (N10E59), and 9255 (N21E64). All are simple and small. IB. Solar Activity Forecast: Solar activity is expected to persist at the low level. IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic field was quiet to active. A prolonged period of southward IMF caused the weak disturbance during the latter half of the interval. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled.
