Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 295 Issued at 2200Z on 22 Oct 2017
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares and a slight chance for an M-class
flare on days one, two, and three (23 Oct, 24 Oct, 25 Oct).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 508 km/s at 21/2219Z. Total IMF reached 8
nT at 22/0008Z. The maximum southward component of Bz reached -5 nT at
21/2321Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 255 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (23 Oct), quiet to minor storm levels
on day two (24 Oct) and active to major storm levels on day three (25
Oct).
