Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 356 Issued at 2200Z on 21 Dec 2012
IA. Analysis of Solar Active Regions and Activity from 20/2100Z to
21/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 3 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low on days
one, two, and three (22 Dec, 23 Dec, 24 Dec).
IIA. Geophysical Activity Summary 20/2100Z to 21/2100Z: 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 522 km/s at
20/2328Z. Total IMF reached 5.1 nT at 20/2150Z. The maximum southward
component of Bz reached -3.3 nT at 20/2218Z. Electrons greater than 2
MeV at geosynchronous orbit reached a peak level of 147 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels for day one (22 Dec) and at quiet to unsettled
levels for days two and three (23 Dec, 24 Dec).
