Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 285 Issued at 2200Z on 12 Oct 2018

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. 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 (13
Oct, 14 Oct, 15 Oct).

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 478 km/s at 12/0128Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 36880 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on day one (13 Oct), quiet to active levels on day
two (14 Oct) and quiet to unsettled levels on day three (15 Oct).
