Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 162 Issued at 2200Z on 11 Jun 2022IA. Analysis of Solar Active Regions and Activity from 10-2100Z to 11-2100Z 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
11/1410Z from Region 3030 (N20E52). There are currently 3 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be low with a
slight chance for an M-class flare on days one, two, and three (12 Jun,
13 Jun, 14 Jun).
IIA. Geophysical Activity Summary 10-2100Z to 11-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 368 km/s at 11/1357Z. Total IMF reached 8
nT at 11/1439Z. The maximum southward component of Bz reached -6 nT at
11/0519Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 150 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one, two, and three (12 Jun, 13 Jun, 14
Jun).
