Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 328 Issued at 2200Z on 24 Nov 2019

IA.  Analysis of Solar Active Regions and Activity from 23/2100Z to
24/2100Z: 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 (25 Nov, 26 Nov, 27 Nov).

IIA.  Geophysical Activity Summary 23/2100Z to 24/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 533 km/s at 23/2144Z. Total IMF reached 6
nT at 23/2132Z. The maximum southward component of Bz reached -4 nT at
24/0826Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 1919 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on days one and two (25 Nov, 26 Nov)
and quiet levels on day three (27 Nov).
