Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 4 Issued at 2200Z on 04 Jan 2013
IA. Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
03/2138Z from Region 1640 (N28W48). There are currently 12 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be at low
levels with a chance for M-class flares on days one, two, and three (05
Jan, 06 Jan, 07 Jan).
IIA. Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 370 km/s at
04/1909Z. Total IMF reached 6.3 nT at 04/0648Z. The maximum southward
component of Bz reached -4.2 nT at 04/0112Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels for the next three days (05 Jan, 06 Jan, 07 Jan).
