Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 193 Issued at 2200Z on 12 Jul 2022

IA.  Analysis of Solar Active Regions and Activity from 11/2100Z to
12/2100Z: Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C7 event observed at
12/0328Z from Region 3056 (S16E37). There are currently 5 numbered
sunspot regions on the disk.
IB.  Solar Activity Forecast: Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
days one, two, and three (13 Jul, 14 Jul, 15 Jul).

IIA.  Geophysical Activity Summary 11/2100Z to 12/2100Z: The geomagnetic
field has been at unsettled to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 529 km/s at 12/1749Z. Total IMF
reached 17 nT at 12/0741Z. The maximum southward component of Bz reached
-14 nT at 12/0652Z.  Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 320 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at unsettled to minor storm levels on day one (13 Jul), quiet to
active levels on day two (14 Jul) and quiet to unsettled levels on day
three (15 Jul). Protons have a slight chance of crossing threshold on
days one, two, and three (13 Jul, 14 Jul, 15 Jul).
