Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 293 Issued at 2200Z on 20 Oct 2017
IA. Analysis of Solar Active Regions and Activity from 19/2100Z to
20/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 0 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 (21
Oct, 22 Oct, 23 Oct).
IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 496 km/s at 19/2100Z. Total IMF reached 5
nT at 19/2156Z. The maximum southward component of Bz reached -4 nT at
20/0206Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 851 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and two (21 Oct, 22 Oct) and
quiet levels on day three (23 Oct).
