:Product: 0109RSGA.txt :Issued: 2012 Jan 09 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 009 Issued at 2200Z on 09 Jan 2012 IA. Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: Solar activity was low. Regions 1391 (N12W12), 1393 (N15W57), and 1395 (N22E45) produced low level C-class flares. Possible umbral separation was observed in the leading spot of Region 1391 and the trailing spot of Region 1393. Both regions have Beta-Gamma magnetic classifications. IB. Solar Activity Forecast: Solar activity is expected to continue at low levels with a chance for M-class activity from Regions 1391 and 1393. IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field was mostly quiet. Solar wind speed at the ACE spacecraft continues to be slightly elevated around 420 - 440 km/s with the IMF Bz not varying much beyond +/- 5 nT. IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be mostly quiet on days 1 - 2 (10 - 11 January). A coronal hole high speed stream is expected to move into geoeffective position on day 3 (12 January) causing quiet to unsettled conditions with a chance for active periods. III.
