Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 324 Issued at 2200Z on 19 Nov 2020
IA. Analysis of Solar Active Regions and Activity from 18/2100Z to
19/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 1 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
on days one, two, and three (20 Nov, 21 Nov, 22 Nov).
IIA. Geophysical Activity Summary 18/2100Z to 19/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 325 km/s at 19/0918Z. Total IMF reached 6 nT at
19/1125Z. The maximum southward component of Bz reached -4 nT at
19/0841Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 238 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (20 Nov), quiet to unsettled levels on
day two (21 Nov) and quiet to active levels on day three (22 Nov).
