Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 152 Issued at 2200Z on 31 May 2020
IA. Analysis of Solar Active Regions and Activity from 30/2100Z to
31/2100Z: 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
with a slight chance for a C-class flare on days one, two, and three (01
Jun, 02 Jun, 03 Jun).
IIA. Geophysical Activity Summary 30/2100Z to 31/2100Z: The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 425 km/s at 31/0029Z. Total IMF reached 7
nT at 30/2105Z. The maximum southward component of Bz reached -6 nT at
30/2126Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 105 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (01 Jun, 02 Jun, 03
Jun).
