Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 338 Issued at 2200Z on 04 Dec 2015
IA. Analysis of Solar Active Regions and Activity from 03/2100Z to
04/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
04/1710Z from Region 2462 (N09E57). There are currently 2 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 on days one, two, and three (05 Dec,
06 Dec, 07 Dec).
IIA. Geophysical Activity Summary 03/2100Z to 04/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
411 km/s at 03/2340Z. Total IMF reached 8 nT at 04/1950Z. The maximum
southward component of Bz reached -6 nT at 04/1924Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 1474 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (05 Dec), quiet to minor
storm levels on day two (06 Dec) and unsettled to minor storm levels on
day three (07 Dec).
