Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 250 Issued at 2200Z on 06 Sep 2016

IA.  Analysis of Solar Active Regions and Activity from 05/2100Z to
06/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 numbered sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (07 Sep,
08 Sep, 09 Sep).

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 reached a peak of 596 km/s at 06/1025Z. Total IMF reached 6
nT at 06/0624Z. The maximum southward component of Bz reached -5 nT at
06/0622Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 23395 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (07 Sep, 08 Sep)
and quiet levels on day three (09 Sep).
