    QUIET

    Geomagnetic conditions are currently quiet, with the planetary K-index holding steady at 1.7. Solar activity remains low despite a moderate F10.7 flux of 118 sfu and a high probability of C-class flares.

    Next 24 h

    Quiet conditions are expected to persist throughout the next 24 hours, with the K-index forecast to drop further to 1.0. No significant geomagnetic disturbances are anticipated, and radio propagation should remain within nominal parameters.

    🌌 Aurora

    Aurora activity is currently low and will remain restricted to high-latitude regions.

    Observers at mid-latitudes should not expect visible displays in the coming 24 hours.

    👁 Watch for

    Monitor the magnetic complexity of active regions AR4493 and AR4494, as their classification suggests a continued potential for impulsive C-class flares despite current stability.
