Solar activity report
Report of Solar-Geophysical Activity 2023 Jul 10 2200 UTCPrepared by the NOAA © SWPC and processed by SpaceWeatherLive.com
Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 191 Issued at 2200Z on 10 Jul 2023IA. Analysis of Solar Active Regions and Activity from 09-2100Z to 10-2100Z Solar activity has been at moderate levels for the past 24
hours. The largest solar event of the period was a M2 event observed at
10/0355Z from Region 3366 (S10W52). There are currently 11 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
days one, two, and three (11 Jul, 12 Jul, 13 Jul).
IIA. Geophysical Activity Summary 09-2100Z to 10-2100Z
The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 495 km/s at 10/0456Z. Total IMF reached 6 nT at
10/1335Z. The maximum southward component of Bz reached -4 nT at
09/2358Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 933 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet levels on day one (11 Jul) and quiet to active levels on
days two and three (12 Jul, 13 Jul). Protons have a slight chance of
crossing threshold on days one, two, and three (11 Jul, 12 Jul, 13 Jul).
