The Joint USAF/NOAA Solar Geophysical Activity Report, issued July 27, 2026, indicates moderate solar activity over the past 24 hours, with six sunspot regions currently visible. Looking ahead, solar activity is expected to be low from July 28-30, though there is a 40% chance for M-class flares and a 10% chance for X-class flares each day.
The geomagnetic field has been at quiet levels but is forecast to become quiet to active on July 28, then quiet to unsettled on July 29 and 30. Middle latitudes have a 30% chance of active conditions and a 10% chance of minor storms on July 28.
High latitudes face a higher probability of geomagnetic disturbances, with a 30% chance of minor storms and a 40% chance of major-severe storms on July 28. This forecast suggests a period of continued vigilance for potential space weather impacts, particularly for high-latitude regions, despite overall low solar activity.
