Report of Solar-Geophysical Activity 2025 Nov 07 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 311 Issued at 2200Z on 07 Nov 2025IA. Analysis of Solar Active Regions and Activity from 06-2100Z to 07-2100Z Solar activity has been at moderate levels for the past 24
hours. There are currently 7 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is expected to be moderate
with a chance for X-class flares on days one, two, and three (08 Nov, 09
Nov, 10 Nov).
IIA. Geophysical Activity Summary 06-2100Z to 07-2100Z
The geomagnetic
field has been at unsettled to minor storm levels for the past 24 hours.
Solar wind speed reached a peak of 859 km/s at 07/1028Z. Total IMF
reached 17 nT at 07/0614Z. The maximum southward component of Bz reached
-16 nT at 07/0539Z. Electrons greater than 2 MeV at geosynchronous
orbit reached a peak level of 340 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at active to major storm levels on day one (08 Nov), quiet to
minor storm levels on day two (09 Nov) and unsettled to major storm
levels on day three (10 Nov). Protons have a slight chance of crossing
threshold on days one, two, and three (08 Nov, 09 Nov, 10 Nov).
