Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 340 Issued at 2200Z on 06 Dec 2018

IA.  Analysis of Solar Active Regions and Activity from 05/2100Z to
06/2100Z: 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
with a slight chance for a C-class flare on days one, two, and three (07
Dec, 08 Dec, 09 Dec).

IIA.  Geophysical Activity Summary 05/2100Z to 06/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 447 km/s at 06/0115Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 135 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to active levels on day one (07 Dec) and quiet to
unsettled levels on days two and three (08 Dec, 09 Dec).
