    Observers in northern Canada and Scandinavia may see intermittent displays, but significant mid-latitude sightings are unlikely given the current downward trend.

    👁 Watch for

    Monitor the Kp-index over the next 6 hours to confirm if the system sustains the current activity or successfully returns to quiet, nominal levels.
