Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 36 Issued at 2200Z on 05 Feb 2015

IA.  Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: 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
05/0953Z from Region 2277 (S08W32). There are currently 3 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare on days one, two, and three (06
Feb, 07 Feb, 08 Feb).

IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z: 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
454 km/s at 04/2217Z. Total IMF reached 7 nT at 05/1640Z. The maximum
southward component of Bz reached -6 nT at 05/1318Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 10953 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (06 Feb, 07 Feb)
and quiet levels on day three (08 Feb).
