    QUIET

    Geomagnetic activity is currently stable at quiet levels with a Kp-index of 2.0. While the solar disk remains relatively calm, a 70% probability for M-class flares suggests a need for ongoing monitoring of active regions.

    Geomagnetic conditions are expected to remain at Kp 2.0 throughout the next 24 hours.

    more

    While the baseline activity is quiet, there remains a persistent 70% chance of M-class flares which could lead to isolated, minor radio degradations on the sunlit side of Earth.

    🌌 Aurora

    Aurora activity is currently restricted to high-latitude regions.

    more

    Observers at mid-latitudes are unlikely to see displays during this quiet period, as current solar wind parameters do not favor significant auroral expansion.

    👁 Watch for

    Monitor AR4498 for any rapid increase in magnetic complexity, which could signal a higher likelihood of significant impulsive solar flares.
