    QUIET

    Geomagnetic conditions remain quiet, though solar flare activity has increased due to an M-class eruption from AR4494. The solar environment is currently stable but bears monitoring for further flaring potential.

    Expect geomagnetic conditions to remain largely quiet through the next 24 hours, with the Kp-index likely rising to 3.0 by the next cycle.

    more

    Further C-class flares are highly probable, with a 50% chance of additional M-class activity as AR4494 transits the solar disk.

    🌌 Aurora

    Aurora visibility is not expected at mid-latitudes (40-60°N) at current activity levels.

    more

    Observers at very high latitudes may see minor activity, but no significant displays are forecast for the next 24 hours.

    👁 Watch for

    Monitor active region AR4494 for any signs of magnetic complexity development that could trigger a stronger, more eruptive solar flare.
