Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 175 Issued at 2200Z on 24 Jun 2022IA. Analysis of Solar Active Regions and Activity from 23-2100Z to 24-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C1 event observed at
23/2210Z from Region 3038 (N16W47). There are currently 4 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a slight chance for an M-class flare on days one, two, and three (25
Jun, 26 Jun, 27 Jun).
IIA. Geophysical Activity Summary 23-2100Z to 24-2100Z

a peak level of 980 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on days one and two (25 Jun, 26 Jun) and
quiet to unsettled levels on day three (27 Jun).
