Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 299 Issued at 2200Z on 26 Oct 2017
IA. Analysis of Solar Active Regions and Activity from 25/2100Z to
26/2100Z: 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 (27
Oct, 28 Oct, 29 Oct).
IIA. Geophysical Activity Summary 25/2100Z to 26/2100Z: The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 607 km/s at 26/0357Z. Total IMF reached 6
nT at 26/0103Z. The maximum southward component of Bz reached -5 nT at
26/0848Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 2154 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on days one and two (27 Oct, 28 Oct) and
quiet to unsettled levels on day three (29 Oct).
