Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 40 Issued at 2200Z on 09 Feb 2015

IA.  Analysis of Solar Active Regions and Activity from 08/2100Z to
09/2100Z: 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
09/0607Z. There are currently 4 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares on days one, two, and three (10 Feb, 11 Feb,
12 Feb).

IIA.  Geophysical Activity Summary 08/2100Z to 09/2100Z: 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
565 km/s at 08/2321Z. Total IMF reached 7 nT at 08/2101Z. The maximum
southward component of Bz reached -5 nT at 09/1943Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 530 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (10 Feb, 11 Feb)
and quiet levels on day three (12 Feb).
