    UNSETTLED

    Geomagnetic conditions are currently unsettled with a Kp-index of 4.0, though levels are expected to trend toward quiet in the coming hours. Solar flare activity remains moderate with a significant probability of C-class events from the current population of active regions.

    Geomagnetic activity is forecast to diminish from Kp 4.0 to Kp 2.0 within the next 6 to 9 hours. Conditions will likely return to quiet levels by midday UTC, with no immediate expectation of geomagnetic storming.

    🌌 Aurora

    At a Kp of 4.0, auroras are unlikely to be visible at mid-latitudes, though high-latitude observers in polar regions may still catch minor activity.

    more

    As the Kp-index drops below 3.0, auroral displays will likely retreat further toward the poles.

    👁 Watch for

    Monitor AR4498 and AR4500 for any sudden increases in magnetic complexity, as these regions represent the highest probability for M-class flare activity in the next 24 hours.
