    Next 24 h

    Expect fluctuating geomagnetic conditions over the next 24 hours. A return to G1 (minor) storm levels is anticipated around 12:00 UTC, followed by a general cooling of geomagnetic indices into the afternoon.

    🌌 Aurora

    Aurora visibility is currently restricted to high latitudes.

    more

    Observers in northern Canada and Scandinavia may experience faint displays, but activity is unlikely to reach lower mid-latitudes at current Kp levels.

    👁 Watch for

    Monitor the development of AR4498, which possesses the magnetic complexity necessary to produce M-class solar flares in the coming 12-24 hours.
