Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 182 Issued at 2200Z on 30 Jun 2024IA. Analysis of Solar Active Regions and Activity from 29-2100Z to 30-2100Z 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
30/0618Z from Region 3734 (N08E59). There are currently 15 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 (01 Jul, 02 Jul,
03 Jul).
IIA. Geophysical Activity Summary 29-2100Z to 30-2100Z
The geomagnetic
field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 586 km/s at 30/2015Z. Total IMF reached 9
nT at 29/2102Z. The maximum southward component of Bz reached -8 nT at
30/0046Z. Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 118 pfu.
IIB. Geophysical Activity Forecast
The geomagnetic field is expected
to be at quiet to active levels on days one, two, and three (01 Jul, 02
Jul, 03 Jul).
