Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 346 Issued at 2200Z on 12 Dec 2015
IA. Analysis of Solar Active Regions and Activity from 11/2100Z to
12/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C7 event observed at
12/1346Z from Region 2470 (N13E76). There are currently 7 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (13 Dec, 14 Dec,
15 Dec).
IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
720 km/s at 12/0103Z. Total IMF reached 5 nT at 11/2215Z. The maximum
southward component of Bz reached -4 nT at 12/0152Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 6196 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (13 Dec, 14 Dec)
and quiet to active levels on day three (15 Dec).
