Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 329 Issued at 2200Z on 25 Nov 2013

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 event of the period was a C2 x-ray event observed at
25/1149Z from Region 1904 (N12W95). With the departure of Region 1904
there are now 3 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 day one (26 Nov) and expected to
be very low with a chance for C-class flares on days two and three (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 362 km/s at
24/2128Z.
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).
