Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 336 Issued at 2200Z on 02 Dec 2017

IA.  Analysis of Solar Active Regions and Activity from 01/2100Z to
02/2100Z: 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 (03 Dec, 04 Dec, 05 Dec).

IIA.  Geophysical Activity Summary 01/2100Z to 02/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 471 km/s at 01/2142Z. Total IMF reached 5
nT at 02/0917Z. The maximum southward component of Bz reached -3 nT at
02/1513Z. Electrons greater than 2 MeV at geosynchronous orbit reached a
peak level of 184 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (03 Dec), quiet to major storm levels
on day two (04 Dec) and active to major storm levels on day three (05
Dec).
