Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 153 Issued at 2200Z on 01 Jun 2020
IA. Analysis of Solar Active Regions and Activity from 31/2100Z to
01/2100Z: Solar activity has been at very low levels for the past 24
hours. There are currently 1 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 day one (02 Jun) and
expected to be very low on days two and three (03 Jun, 04 Jun).
IIA. Geophysical Activity Summary 31/2100Z to 01/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 435 km/s at 31/2236Z. Total IMF reached 6 nT at
01/2042Z. The maximum southward component of Bz reached -6 nT at
01/2030Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 176 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one, two, and three (02 Jun, 03 Jun, 04
Jun).
