Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 245 Issued at 2200Z on 02 Sep 2017
IA. Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C7 event observed at
02/1541Z from Region 2672 (N08W98). There are currently 4 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 (03
Sep, 04 Sep, 05 Sep).
IIA. Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 721 km/s at 02/0239Z. Total IMF
reached 9 nT at 01/2335Z. The maximum southward component of Bz reached
-7 nT at 02/0326Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 7573 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (03 Sep) and quiet to
unsettled levels on days two and three (04 Sep, 05 Sep).
