Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 39 Issued at 2200Z on 08 Feb 2016

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 C1 event observed at
08/0529Z from Region 2492 (N14W19). There are currently 5 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 (09 Feb,
10 Feb, 11 Feb).

IIA.  Geophysical Activity Summary 07/2100Z to 08/2100Z: 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 466 km/s at 08/0757Z. Total IMF reached 10 nT at 08/0600Z. The
maximum southward component of Bz reached -9 nT at 08/0349Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and three (09 Feb, 11 Feb)
and quiet to unsettled levels on day two (10 Feb).
