Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 5 Issued at 2200Z on 05 Jan 2013
IA. Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
05/0931Z from Region 1652 (N20E74). There are currently 14 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 (06
Jan, 07 Jan, 08 Jan).
IIA. Geophysical Activity Summary 04/2100Z to 05/2100Z: 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 361 km/s at
04/2209Z. Total IMF reached 5.2 nT at 05/1138Z. The maximum southward
component of Bz reached -3.5 nT at 04/2306Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet on day 1 (06 Jan). Quiet to unsettled levels are
expected on days 2-3 (07 Jan, 08 Jan).
