Conditions are expected to transition to unsettled, with the Kp-index forecast to reach 4.0 by early August 2nd.

more

Radio communication remains stable, though the 65% probability of M-class flares warrants monitoring for potential sudden ionospheric disturbances.

🌌 Aurora

Aurora activity will remain confined to high latitudes.

more

Observers at mid-latitudes are unlikely to see displays, as geomagnetic indices are not forecasted to reach storm thresholds.

👁 Watch for

Watch for potential M-class flare activity from the maturing active regions, which could trigger R1-level radio blackouts on the sunlit side of Earth.
