Joint USAF/NOAA Report of Solar and Geophysical Activity

SDF Number 184 Issued at 2200Z on 03 Jul 2023

IA. Analysis of Solar Active Regions and Activity from 02-2100Z to 03-2100Z

Solar activity has been at high levels for the past 24 hours. The largest solar event of the period was a X1 event observed at 02/2314Z from Region 3354 (N16W58). There are currently 6 numbered sunspot regions on the disk.
IB. Solar Activity Forecast
Solar activity is likely to be moderate with a chance for X-class flares on days one, two, and three (04 Jul, 05 Jul, 06 Jul).
IIA. Geophysical Activity Summary 02-2100Z to 03-2100Z
The geomagnetic field has been at quiet levels for the past 24 hours. Solar wind speed reached a peak of 476 km/s at 03/2016Z. Total IMF reached 7 nT at 03/0612Z. The maximum southward component of Bz reached -5 nT at 03/1830Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 3083 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to unsettled levels on days one and two (04 Jul, 05 Jul) and quiet levels on day three (06 Jul). Protons have a chance of crossing threshold on days one, two, and three (04 Jul, 05 Jul, 06 Jul).
