Solar activity report
Report of Solar-Geophysical Activity 2022 Nov 15 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 319 Issued at 2200Z on 15 Nov 2022IA. Analysis of Solar Active Regions and Activity from 14-2100Z to 15-2100Z 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
15/0251Z from Region 3140 (N25W76). 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 and two (16 Nov, 17 Nov) and likely to be low with a slight
chance for an M-class flare on day three (18 Nov).
IIA. Geophysical Activity Summary 14-2100Z to 15-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 475 km/s at 15/0555Z. Total IMF reached 5 nT at
14/2119Z. The maximum southward component of Bz reached -3 nT at
15/0414Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 414 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on days one and three (16 Nov, 18
Nov) and quiet levels on day two (17 Nov). Protons greater than 10 Mev
have a slight chance of crossing threshold on days one and two (16 Nov,
17 Nov).
