Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 324 Issued at 2200Z on 20 Nov 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
on days one, two, and three (21 Nov, 22 Nov, 23 Nov).
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 397 km/s at 20/2048Z. Total IMF reached 10
nT at 20/1622Z. The maximum southward component of Bz reached -9 nT at
20/1621Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 3310 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to active levels on day one (21 Nov), quiet to active
levels on day two (22 Nov) and quiet to unsettled levels on day three
(23 Nov).
