Solar activity report
Report of Solar-Geophysical Activity 2022 Oct 12 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 285 Issued at 2200Z on 12 Oct 2022IA. Analysis of Solar Active Regions and Activity from 11-2100Z to 12-2100Z Solar activity has been at low levels for the past 24 hours.
The largest solar event of the period was a C3 event observed at
11/2121Z from Region 3119 (N28W18). There are currently 4 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be low with
a chance for M-class flares and a slight chance for an X-class flare on
days one, two, and three (13 Oct, 14 Oct, 15 Oct).
IIA. Geophysical Activity Summary 11-2100Z to 12-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
averaged ~375 km/s. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 6216 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on days one and two (13 Oct, 14 Oct) and quiet to
unsettled levels on day three (15 Oct). Protons have a slight chance of
crossing threshold on days one, two, and three (13 Oct, 14 Oct, 15 Oct).
