Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 207 Issued at 2200Z on 26 Jul 2022IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C8 event observed at
26/1535Z from Region 3060 (N12W89). There are currently 6 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (27 Jul,
28 Jul, 29 Jul).
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z

a peak level of 1229 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (27 Jul, 29
Jul) and quiet levels on day two (28 Jul).
