Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 339 Issued at 2200Z on 04 Dec 2012
IA. Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 4 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be at very
low to low levels on days one, two, and three (05 Dec, 06 Dec, 07 Dec).
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 462 km/s at
04/1430Z. Total IMF reached 11.7 nT at 04/0005Z. The maximum southward
component of Bz reached -10.9 nT at 04/0447Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels for the next three days (05 Dec, 06 Dec, 07 Dec).
