Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 143 Issued at 2200Z on 22 May 2020
IA. Analysis of Solar Active Regions and Activity from 21/2100Z to
22/2100Z: 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 (23 May, 24 May, 25 May).
IIA. Geophysical Activity Summary 21/2100Z to 22/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 377 km/s at 22/2021Z. Total IMF reached 6 nT at
22/1101Z. The maximum southward component of Bz reached -5 nT at
22/1408Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 153 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (23 May, 24 May, 25
May).
