Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 234 Issued at 2200Z on 22 Aug 2017
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: 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
22/1750Z from Region 2671 (N10W31). 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 (23 Aug,
24 Aug, 25 Aug).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet to major storm levels for the past 24 hours.
Solar wind speed reached a peak of 684 km/s at 22/0656Z. Total IMF
reached 9 nT at 22/0149Z. The maximum southward component of Bz reached
-9 nT at 22/0149Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 31128 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (23 Aug), quiet to unsettled
levels on day two (24 Aug) and quiet levels on day three (25 Aug).
