Report of Solar-Geophysical Activity 2025 Nov 30 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 334 Issued at 2200Z on 30 Nov 2025IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z Solar activity has been at moderate levels for the past 24
hours. There are currently 6 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
(01 Dec, 02 Dec, 03 Dec).
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic
field has been at quiet to active levels for the past 24 hours. Solar
wind speed reached a peak of 657 km/s at 30/0231Z. Total IMF reached 6
nT at 30/0152Z. The maximum southward component of Bz reached -6 nT at
30/0102Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 8309 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to unsettled levels on day one (01 Dec), quiet levels on
day two (02 Dec) and quiet to active levels on day three (03 Dec).
Protons have a slight chance of crossing threshold on days one, two, and
three (01 Dec, 02 Dec, 03 Dec).
