Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 344 Issued at 2200Z on 10 Dec 2015
IA. Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C3 event observed at
10/0750Z from Region 2468 (S15E65). There are currently 6 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (11 Dec,
12 Dec, 13 Dec).
IIA. Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed, as measured by the ACE spacecraft, reached a peak
speed of 711 km/s at 10/2058Z. Total IMF reached 11 nT at 10/0556Z. The
maximum southward component of Bz reached -9 nT at 10/0733Z. Electrons
greater than 2 MeV at geosynchronous orbit reached a peak level of 3235
pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to minor storm levels on day one (11 Dec) and quiet
to active levels on days two and three (12 Dec, 13 Dec).
