Solar activity report
Report of Solar-Geophysical Activity 2022 Mar 25 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 84 Issued at 2200Z on 25 Mar 2022IA. Analysis of Solar Active Regions and Activity from 24-2100Z to 25-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M1 event observed at
25/0526Z from Region 2974 (S19E23). There are currently 3 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be very low
with a chance for a C-class flares on days one, two, and three (26 Mar,
27 Mar, 28 Mar).
IIA. Geophysical Activity Summary 24-2100Z to 25-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 525 km/s at 25/0000Z. Total IMF reached 5
nT at 25/1127Z. The maximum southward component of Bz reached -4 nT at
25/1705Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 194 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on days one and three (26 Mar, 28 Mar)
and quiet to minor storm levels on day two (27 Mar).
