Solar activity report
Report of Solar-Geophysical Activity 2024 Nov 14 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 14 Nov 2024IA. Analysis of Solar Active Regions and Activity from 13-2100Z to 14-2100Z 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
13/2259Z from Region 3886 (S07W62). There are currently 5 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
(15 Nov, 16 Nov, 17 Nov).
IIA. Geophysical Activity Summary 13-2100Z to 14-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 448 km/s at 14/1252Z. Total IMF reached 13
nT at 14/0605Z. The maximum southward component of Bz reached -12 nT at
14/1614Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 196 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on day one (15 Nov) and quiet to
unsettled levels on days two and three (16 Nov, 17 Nov). Protons have a
slight chance of crossing threshold on days one, two, and three (15 Nov,
16 Nov, 17 Nov).
