Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 342 Issued at 2200Z on 08 Dec 2015
IA. Analysis of Solar Active Regions and Activity from 07/2100Z to
08/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C6 event observed at
08/1914Z from Region 2463 (S09E06). There are currently 4 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare on days one, two, and three (09 Dec, 10 Dec, 11 Dec).
IIA. Geophysical Activity Summary 07/2100Z to 08/2100Z: 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
712 km/s at 07/2354Z. Total IMF reached 6 nT at 08/0028Z. The maximum
southward component of Bz reached -5 nT at 08/0037Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 8733 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (09 Dec), active to minor
storm levels on day two (10 Dec) and unsettled to minor storm levels on
day three (11 Dec).
