Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 351 Issued at 2200Z on 16 Dec 2012
IA. Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: Solar activity was at low levels due to a single C1 x-ray
event at 16/2103Z from Region 1631 (N20W60). There are currently 4
numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare for days one through three (17 - 19
December).
IIA. Geophysical Activity Summary 15/2100Z to 16/2100Z: 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 463 km/s at
16/1937Z. Total IMF reached 9.4 nT at 16/0235Z. The maximum southward
component of Bz reached -6.5 nT at 16/0827Z.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels for days one through three (17 - 19
December) with a chance for active periods on 17 December.
