Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 360 Issued at 2200Z on 25 Dec 2012
IA. Analysis of Solar Active Regions and Activity from 24/2100Z to
25/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
25/1304Z from Region 1635 (N11W17). There are currently 3 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be at low
levels on days one, two, and three (26 Dec, 27 Dec, 28 Dec).
IIA. Geophysical Activity Summary 24/2100Z to 25/2100Z: 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 344 km/s at
25/0252Z. Total IMF reached 5.3 nT at 25/0334Z. The maximum southward
component of Bz reached -3.9 nT at 25/1629Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels for the next two days (26 - 27 December). By day
three (28 December), activity is expected to increase to quiet to
unsettled levels.
