Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 304 Issued at 2200Z on 31 Oct 2014

IA.  Analysis of Solar Active Regions and Activity from 30/2100Z to
31/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C8 event observed at
31/0101Z. There are currently 6 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be low with
a slight chance for an M-class flare on day one (01 Nov) and likely to
be low on days two and three (02 Nov, 03 Nov).

IIA.  Geophysical Activity Summary 30/2100Z to 31/2100Z: 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 531 km/s at
31/1928Z. Total IMF reached 12 nT at 31/1229Z. The maximum southward
component of Bz reached -8 nT at 31/1824Z. Electrons greater than 2 MeV
at geosynchronous orbit reached a peak level of 1475 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one, two, and three (01 Nov,
02 Nov, 03 Nov).
