Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 296 Issued at 2200Z on 23 Oct 2017
IA. Analysis of Solar Active Regions and Activity from 22/2100Z to
23/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 2 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 on days one and two (24 Oct, 25 Oct)
and expected to be very low with a slight chance for a C-class flare on
day three (26 Oct).
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 413 km/s at 23/0425Z. Total IMF reached 7
nT at 23/0046Z. The maximum southward component of Bz reached -3 nT at
23/0649Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 518 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (24 Oct), active to
major storm levels on day two (25 Oct) and unsettled to minor storm
levels on day three (26 Oct).
