Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 95 Issued at 2200Z on 05 Apr 2022IA. Analysis of Solar Active Regions and Activity from 04-2100Z to 05-2100Z 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
05/0758Z from Region 2978 (S17W37). There are currently 5 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 (06 Apr,
07 Apr, 08 Apr).
IIA. Geophysical Activity Summary 04-2100Z to 05-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 483 km/s at 05/0645Z. Total IMF reached 7 nT at
05/1114Z. The maximum southward component of Bz reached -4 nT at
05/0638Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 2903 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to minor storm levels on days one and two (06 Apr, 07
Apr) and quiet to unsettled levels on day three (08 Apr).
