Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 12 Issued at 2200Z on 12 Jan 2017

IA.  Analysis of Solar Active Regions and Activity from 11/2100Z to
12/2100Z: 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
12/1618Z. There are currently 1 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 (13 Jan,
14 Jan, 15 Jan).

IIA.  Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 437 km/s at 11/2135Z. Total IMF reached 5
nT at 12/1835Z. The maximum southward component of Bz reached -3 nT at
12/1737Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 7626 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (13 Jan, 14 Jan)
and quiet levels on day three (15 Jan).
