Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 57 Issued at 2200Z on 26 Feb 2022IA. Analysis of Solar Active Regions and Activity from 25-2100Z to 26-2100Z
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
25/2140Z. There are currently 2 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 days one, two, and three (27
Feb, 28 Feb, 01 Mar).
IIA. Geophysical Activity Summary 25-2100Z to 26-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 435 km/s at 25/2117Z. Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 1219 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (27 Feb) and quiet to
active levels on days two and three (28 Feb, 01 Mar).
