Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 346 Issued at 2200Z on 11 Dec 2012
IA. Analysis of Solar Active Regions and Activity from 10/2100Z to
11/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be at very
low levels with a chance for C-class flares on days one, two, and three
(12 Dec, 13 Dec, 14 Dec).
IIA. Geophysical Activity Summary 10/2100Z to 11/2100Z: 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 328 km/s at
10/2344Z. Total IMF reached 5.9 nT at 10/2146Z. The maximum southward
component of Bz reached -4.9 nT at 10/2149Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (12 Dec), quiet to unsettled levels on
day two (13 Dec), and a return to quiet levels on day three (14 Dec).
