Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 364 Issued at 2200Z on 29 Dec 2012
IA. Analysis of Solar Active Regions and Activity from 28/2100Z to
29/2100Z: 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
29/1933Z from Region 1638 (N12E43). There are currently 4 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare for days 1-3 (30 Dec, 31 Dec, 01
Jan).
IIA. Geophysical Activity Summary 28/2100Z to 29/2100Z: 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 349 km/s at
29/0722Z. Total IMF reached 6.7 nT at 29/0318Z. The maximum southward
component of Bz reached -5.9 nT at 29/0319Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days 1-2 (30 Dec, 31 Dec). Quiet to unsettled
levels with a slight chance for an isolated active period is expected on
day 3 (01 Jan).
