Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 317 Issued at 2200Z on 12 Nov 2020
IA. Analysis of Solar Active Regions and Activity from 11/2100Z to
12/2100Z: Solar activity has been at very low levels for the past 24
hours. The largest solar event of the period was a C1 event observed at
12/0227Z. There are currently 2 numbered sunspot regions on the disk.
IB. Solar Activity Forecast: Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (13 Nov,
14 Nov, 15 Nov).
IIA. Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 435 km/s at 12/2027Z. Total IMF reached 10 nT at
11/2117Z. The maximum southward component of Bz reached -1 nT at
12/1909Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 535 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (13 Nov) and quiet to unsettled levels
on days two and three (14 Nov, 15 Nov).
