Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 263 Issued at 2200Z on 20 Sep 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 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 (21
Sep, 22 Sep, 23 Sep).
IIA. Geophysical Activity Summary 19/2100Z to 20/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 533 km/s at 19/2118Z. Total IMF reached 6
nT at 20/2016Z. The maximum southward component of Bz reached -4 nT at
20/1158Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 33761 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (21 Sep, 23
Sep) and quiet levels on day two (22 Sep).
