Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 244 Issued at 2200Z on 01 Sep 2022

IA. Analysis of Solar Active Regions and Activity from 31-2100Z to 01-2100Z

Solar activity has been at low levels for the past 24 hours. The largest solar event of the period was a C4 event observed at 01/1358Z from Region 3092 (S09E67). There are currently 4 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with a chance for M-class flares on days one, two, and three (02 Sep, 03 Sep, 04 Sep).
IIA. Geophysical Activity Summary 31-2100Z to 01-2100Z
The geomagnetic field has been at quiet to active levels for the past 24 hours. Solar wind speed reached a peak of 601 km/s at 01/0553Z. Total IMF reached 8 nT at 31/2232Z. The maximum southward component of Bz reached -7 nT at 31/2227Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 170 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on day one (02 Sep), quiet to active levels on day two (03 Sep) and unsettled to major storm levels on day three (04 Sep). Protons greater than 10 Mev have a slight chance of crossing threshold on days two and three (03 Sep, 04 Sep).
