Solar activity report
Report of Solar-Geophysical Activity 2024 Nov 09 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 314 Issued at 2200Z on 09 Nov 2024IA. Analysis of Solar Active Regions and Activity from 08-2100Z to 09-2100Z
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
09/2050Z from Region 3889 (S10E41). There are currently 7 numbered
sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be moderate
with a slight chance for an X-class flare on days one, two, and three
(10 Nov, 11 Nov, 12 Nov).
IIA. Geophysical Activity Summary 08-2100Z to 09-2100Z
The geomagnetic
field has been at active to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 494 km/s at 09/0804Z. Total IMF
reached 21 nT at 09/0806Z. The maximum southward component of Bz reached
-13 nT at 09/1057Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 129 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on days one and two (10 Nov, 11 Nov) and
quiet to unsettled levels on day three (12 Nov). Protons have a slight
chance of crossing threshold on days one, two, and three (10 Nov, 11
Nov, 12 Nov).
