Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 320 Issued at 2200Z on 16 Nov 2019

IA.  Analysis of Solar Active Regions and Activity from 15/2100Z to
16/2100Z: 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 (17 Nov, 18 Nov, 19 Nov).

IIA.  Geophysical Activity Summary 15/2100Z to 16/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 424 km/s at 16/1903Z. Total IMF reached 9 nT at
16/1812Z. The maximum southward component of Bz reached -7 nT at
16/1704Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 283 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to unsettled levels on day one (17 Nov) and quiet levels
on days two and three (18 Nov, 19 Nov).
