SDF Number 322 Issued at 2200Z on 17 Nov 2020
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 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 (18 Nov, 19 Nov, 20 Nov).
IIA. Geophysical Activity Summary 16/2100Z to 17/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 327 km/s at 17/1215Z. Total IMF reached 6 nT at
17/2048Z. The maximum southward component of Bz reached -3 nT at
17/0836Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 275 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (18 Nov, 19 Nov, 20
Nov).
