Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 236 Issued at 2200Z on 24 Aug 2017
IA. Analysis of Solar Active Regions and Activity from 23/2100Z to
24/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C3 event observed at
24/0037Z from Region 2671 (N11W56). 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 (25 Aug,
26 Aug, 27 Aug).
IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 469 km/s at 23/2153Z. Total IMF reached 5
nT at 24/1018Z. The maximum southward component of Bz reached -5 nT at
24/1008Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 3701 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (25 Aug) and quiet levels
on days two and three (26 Aug, 27 Aug).
