Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 321 Issued at 2200Z on 17 Nov 2017
IA. Analysis of Solar Active Regions and Activity from 16/2100Z to
17/2100Z: 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 (18
Nov, 19 Nov, 20 Nov).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 514 km/s at 16/2314Z. Total IMF reached 5
nT at 16/2252Z. The maximum southward component of Bz reached -4 nT at
17/0859Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 2332 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (18 Nov) and unsettled to
active levels on days two and three (19 Nov, 20 Nov).
