Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 226 Issued at 2200Z on 14 Aug 2022IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C5 event observed at
14/1400Z from Region 3079 (S11W39). There are currently 6 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 (15 Aug, 16 Aug,
17 Aug).
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 530 km/s at 14/0010Z. Total IMF reached 6
nT at 14/1820Z. The maximum southward component of Bz reached -5 nT at
14/0036Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 3058 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one and two (15 Aug, 16 Aug) and quiet to
minor storm levels on day three (17 Aug).
