Joint USAF/NOAA Report of Solar and Geophysical Activity
SDF Number 187 Issued at 2200Z on 06 Jul 2026IA. Analysis of Solar Active Regions and Activity from 05-2100Z to 06-2100Z Solar activity has been at moderate levels for the past 24
hours. 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 day one (07 Jul) and
expected to be low with a slight chance for an M-class flare on days two
and three (08 Jul, 09 Jul).

field has been at quiet to unsettled levels for the past 24 hours. Solar
wind speed reached a peak of 540 km/s at 06/1800 UTC. Total IMF reached
08 nT at 06/1908 UTC. The maximum southward component of Bz reached -04
nT at 06/1708 UTC. Electrons greater than 2 MeV at geosynchronous orbit
reached a peak level of 1935 pfu.

The geomagnetic field is expected
to be at quiet levels on days one and two (07 Jul, 08 Jul) and quiet to
active levels on day three (09 Jul).
