Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 114 Issued at 2200Z on 23 Apr 2020
IA. Analysis of Solar Active Regions and Activity from 22/2100Z to
23/2100Z: 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 (24 Apr, 25 Apr, 26 Apr).
IIA. Geophysical Activity Summary 22/2100Z to 23/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 449 km/s at 22/2300Z. Total IMF reached 5 nT at
23/2057Z. The maximum southward component of Bz reached -2 nT at
23/0145Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 342 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (24 Apr, 25 Apr, 26
Apr).
