Solar activity report
Report of Solar-Geophysical Activity 2022 Nov 16 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 320 Issued at 2200Z on 16 Nov 2022IA. Analysis of Solar Active Regions and Activity from 15-2100Z to 16-2100Z 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
16/0538Z from Region 3140 (N23W89). There are currently 6 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
day one (17 Nov) and likely to be low with a chance for M-class flares
on day two (18 Nov) and expected to be very low with a chance for a
C-class flares on day three (19 Nov).
IIA. Geophysical Activity Summary 15-2100Z to 16-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 402 km/s at 15/2103Z. Total IMF reached 5 nT at
15/2106Z. The maximum southward component of Bz reached -4 nT at
15/2224Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 342 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on day one (17 Nov), quiet to unsettled levels on
day two (18 Nov) and quiet to active levels on day three (19 Nov).
Protons greater than 10 Mev have a slight chance of crossing threshold
on day one (17 Nov).
