Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 246 Issued at 2200Z on 03 Sep 2017
IA. Analysis of Solar Active Regions and Activity from 02/2100Z to
03/2100Z: 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
02/2203Z from Region 2672 (N08W98). There are currently 5 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 days one, two, and three (04
Sep, 05 Sep, 06 Sep).
IIA. Geophysical Activity Summary 02/2100Z to 03/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 587 km/s at 02/2116Z. Total IMF reached 5
nT at 02/2212Z. The maximum southward component of Bz reached -3 nT at
02/2222Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 12319 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (04 Sep, 05 Sep)
and quiet levels on day three (06 Sep).
