A joint report from the U.S. Air Force (USAF) and the National Oceanic and Atmospheric Administration (NOAA) indicates moderate solar activity and quiet geomagnetic conditions, with forecasts predicting low solar activity and unsettled to active geomagnetic fields over the next three days.
The report, issued on July 26, 2026, noted six numbered sunspot regions on the solar disk. Solar activity is expected to remain low, though there is a 45% chance for M-class flares and a 10% chance for X-class flares daily from July 27 to July 29.
Geomagnetic activity was quiet, with solar wind speed peaking at 548 km/s and geosynchronous electrons reaching 1159 pfu. The geomagnetic field is forecast to be unsettled to active on July 27, quiet to active on July 28, and quiet to unsettled on July 29. Middle latitudes face a 20% chance of minor storms on July 27, while high latitudes have a 30% chance of minor storms and a 55% chance of active conditions on the same day.
