Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 217 Issued at 2200Z on 05 Aug 2014

IA.  Analysis of Solar Active Regions and Activity from 04/2100Z to
05/2100Z: 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
05/2027Z from Region 2132 (S21W07). There are currently 4 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 (06 Aug, 07 Aug,
08 Aug).

IIA.  Geophysical Activity Summary 04/2100Z to 05/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed, as measured by the ACE spacecraft, reached a peak speed of
526 km/s at 05/1720Z. Total IMF reached 8 nT at 04/2104Z. The maximum
southward component of Bz reached -6 nT at 05/0505Z.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (06 Aug) and quiet to unsettled levels
on days two and three (07 Aug, 08 Aug).
