Solar activity report
Report of Solar-Geophysical Activity 2022 Oct 19 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 292 Issued at 2200Z on 19 Oct 2022IA. Analysis of Solar Active Regions and Activity from 18-2100Z to 19-2100Z 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
18/2146Z from Region 3124 (S34W68). There are currently 4 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 (20 Oct,
21 Oct, 22 Oct).
IIA. Geophysical Activity Summary 18-2100Z to 19-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 516 km/s at 18/2115Z. Total IMF reached 5 nT at
18/2213Z. The maximum southward component of Bz reached -4 nT at
19/0428Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 913 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on day one (20 Oct), quiet to unsettled
levels on day two (21 Oct) and quiet levels on day three (22 Oct).
