Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 289 Issued at 2200Z on 15 Oct 2020

IA.  Analysis of Solar Active Regions and Activity from 14/2100Z to
15/2100Z: 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 (16
Oct, 17 Oct, 18 Oct).

IIA.  Geophysical Activity Summary 14/2100Z to 15/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 309 km/s at 15/2032Z. Total IMF reached 7 nT at
15/1836Z. The maximum southward component of Bz reached -2 nT at
15/2049Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 210 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (16 Oct, 17 Oct, 18
Oct).
