Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 15 Issued at 2200Z on 15 Jan 2022IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z 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
15/0854Z from Region 2932 (N32E60). There are currently 8 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a slight chance for an M-class flare on day one (16 Jan) and likely to
be low with a slight chance for an M-class flare on days two and three
(17 Jan, 18 Jan).
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic
field has been at quiet to major storm levels for the past 24 hours.
Solar wind speed reached a peak of 627 km/s at 15/1944Z. Total IMF
reached 17 nT at 14/2114Z. The maximum southward component of Bz reached
-17 nT at 14/2114Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 166 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to minor storm levels on day one (16 Jan), unsettled to
active levels on day two (17 Jan) and quiet to unsettled levels on day
three (18 Jan).
