The Kp-index is forecast to rise slightly to 3.0 by early October 26th, reflecting a return to unsettled but non-storming conditions.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes.

Observers in extreme northern latitudes may see only faint, low-level auroral activity consistent with baseline solar conditions.

👁 Watch for

Monitor the F10.7 radio flux for any sudden changes, as a decrease below 100 sfu would signal a shift into a period of even lower solar activity.
