Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 159 Issued at 2200Z on 08 Jun 2022IA. Analysis of Solar Active Regions and Activity from 07-2100Z to 08-2100Z
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 (09
Jun, 10 Jun, 11 Jun).
IIA. Geophysical Activity Summary 07-2100Z to 08-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 336 km/s at 08/1652Z. Total IMF reached 10 nT at
08/0637Z. The maximum southward component of Bz reached -7 nT at
08/0817Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 106 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (09 Jun, 10 Jun, 11
Jun).
