Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 354 Issued at 2200Z on 19 Dec 2012
IA. Analysis of Solar Active Regions and Activity from 18/2100Z to
19/2100Z: 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 expected to be at low
levels on days one, two, and three (20 Dec, 21 Dec, 22 Dec).
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: 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 around 500 km/s.
Total IMF reached 5.3 nT at 19/1125Z. The maximum southward component of
Bz reached -3.4 nT at 19/0811Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 481 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels for the next three days (20 Dec, 21 Dec, 22 Dec).
