Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 160 Issued at 2200Z on 09 Jun 2022
IA. Analysis of Solar Active Regions and Activity from 08/2100Z to 09/2100Z: 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 09/1018Z. There are currently 1 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 day one (10 Jun) and expected to be very low with a chance for a C-class flares on days two and three (11 Jun, 12 Jun).
IIA. Geophysical Activity Summary 08/2100Z to 09/2100Z: The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 337 km/s at 09/0259Z. Total IMF reached 6 nT at 09/1001Z. The maximum southward component of Bz reached -6 nT at 09/1001Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 206 pfu.
IIB. Geophysical Activity Forecast: The geomagnetic field is expected to be at quiet levels on days one, two, and three (10 Jun, 11 Jun, 12 Jun).
