Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 278 Issued at 2200Z on 05 Oct 2013

IA.  Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 5 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 day one (06 Oct) and likely to be
low with a slight chance for an M-class flare on days two and three (07
Oct, 08 Oct).

IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z: 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 374 km/s at
04/2127Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 673 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (06 Oct, 07 Oct)
and quiet levels on day three (08 Oct).
