Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 146 Issued at 2200Z on 25 May 2020

IA.  Analysis of Solar Active Regions and Activity from 24/2100Z to
25/2100Z: 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 (26 May, 27 May, 28 May).

IIA.  Geophysical Activity Summary 24/2100Z to 25/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 349 km/s at 25/0430Z. Total IMF reached 7 nT at
24/2244Z. The maximum southward component of Bz reached -6 nT at
24/2254Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 197 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (26 May, 27 May, 28
May).
