Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 329 Issued at 2200Z on 25 Nov 2014

IA.  Analysis of Solar Active Regions and Activity from 24/2100Z to
25/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C2 event observed at
24/2221Z from Region 2217 (S19E53). There are currently 6 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 (26 Nov, 27 Nov,
28 Nov).

IIA.  Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed,
as measured by the ACE spacecraft, reached a peak speed of 432 km/s at
25/0730Z. Total IMF reached 6 nT at 24/2158Z. The maximum southward
component of Bz reached -5 nT at 25/0721Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 463 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (26 Nov, 27 Nov)
and quiet levels on day three (28 Nov). Protons greater than 10 Mev have
a slight chance of crossing threshold on day one (26 Nov).
