Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 180 Issued at 2200Z on 29 Jun 2026

IA.  Analysis of Solar Active Regions and Activity from 28/2100Z to
29/2100Z: Solar activity has been at low 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 days one, two, and three
(30 Jun, 01 Jul, 02 Jul).

IIA.  Geophysical Activity Summary 28/2100Z to 29/2100Z: The geomagnetic
field has been at quiet levels for the past 24 hours. Solar wind speed
reached a peak of 508 km/s at 29/1514Z.  Electrons greater than 2 MeV at
geosynchronous orbit reached a peak level of 2893 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet to minor storm levels on day one (30 Jun) and quiet to
active levels on days two and three (01 Jul, 02 Jul). Protons greater
than 10 Mev have a slight chance of crossing threshold on day three (02
Jul).
