Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 297 Issued at 2200Z on 24 Oct 2017
IA. Analysis of Solar Active Regions and Activity from 23/2100Z to
24/2100Z: 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 slight chance for a C-class flare on days one, two, and three (25
Oct, 26 Oct, 27 Oct).
IIA. Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic
field has been at quiet to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 641 km/s at 24/2012Z. Total IMF
reached 15 nT at 24/1140Z. The maximum southward component of Bz reached
-9 nT at 24/1017Z. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 2102 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at active to major storm levels on day one (25 Oct), unsettled to
minor storm levels on day two (26 Oct) and unsettled to active levels on
day three (27 Oct).
