SDF Number 185 Issued at 2200Z on 03 Jul 2024

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

Solar activity has been at moderate levels for the past 24 hours. The largest solar event of the period was a M1 event observed at 03/0741Z from Region 3729 (S05W26). 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 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 412 km/s at 03/1748Z. Total IMF reached 6 nT at 03/1530Z. The maximum southward component of Bz reached -3 nT at 03/0404Z. Electrons greater than 2 MeV at geosynchronous orbit reached a peak level of 1192 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected to be at quiet to active levels on day one (04 Jul), quiet to unsettled levels on day two (05 Jul) and quiet levels on day three (06 Jul).
