Joint USAF/NOAA Solar Geophysical Activity Report and Forecast
SDF Number 180 Issued at 2200Z on 29 Jun 2025

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 10 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 (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 697 km/s at 29/0652Z. Total IMF reached 5 nT at
29/1824Z. The maximum southward component of Bz reached -4 nT at
29/1629Z.  Electrons greater than 2 MeV at geosynchronous orbit reached
a peak level of 6349 pfu.
IIB.  Geophysical Activity Forecast: The geomagnetic field is expected
to be at quiet levels on days one and two (30 Jun, 01 Jul) and quiet to
active levels on day three (02 Jul).
