Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 104 Issued at 2200Z on 13 Apr 2020
IA. Analysis of Solar Active Regions and Activity from 12/2100Z to
13/2100Z: 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 (14 Apr, 15 Apr, 16 Apr).
IIA. Geophysical Activity Summary 12/2100Z to 13/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 429 km/s at 13/0225Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 158 pfu.
