Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 187 Issued at 2200Z on 06 Jul 2013

IA.  Analysis of Solar Active Regions and Activity from 05/2100Z to
06/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C4 event observed at
06/0233Z from Region 1785 (S11E12). There are currently 4 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one, two, and three
(07 Jul, 08 Jul, 09 Jul).

IIA.  Geophysical Activity Summary 05/2100Z to 06/2100Z: 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
384 km/s at 06/1141Z. Total IMF reached 13 nT at 06/0059Z. The maximum
southward component of Bz reached -12 nT at 06/0253Z. Electrons greater
than 2 MeV at geosynchronous orbit reached a peak level of 480 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (07 Jul) and quiet to
unsettled levels on days two and three (08 Jul, 09 Jul).
