Report of Solar Geophysical Activity (RSGA)

Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 283 Issued at 2200Z on 10 Oct 2013

IA.  Analysis of Solar Active Regions and Activity from 09/2100Z to
10/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
10/1101Z from Region 1861 (S10E22). There are currently 8 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 (11 Oct, 12 Oct,
13 Oct).

IIA.  Geophysical Activity Summary 09/2100Z to 10/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
498 km/s at 09/2102Z. Total IMF reached 11 nT at 09/2158Z. The maximum
southward component of Bz reached -7 nT at 10/0006Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 115 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (11 Oct, 12 Oct)
and quiet levels on day three (13 Oct).
