    Geomagnetic conditions are currently quiet with a Kp-index near zero. Solar activity is characterized by steady, moderate flare production, primarily driven by AR4420.

    The Earth’s magnetic field is undisturbed, with the Kp-index holding at 0.3. The solar disk contains 31 active regions, with AR4420 identified as the primary source of recent M-class flare activity. F10.7 flux is measured at 107.0 sfu, indicating a moderate level of solar radio output consistent with typical levels for this phase of the cycle.

    Key Metric

    The 55% probability of M-class flares from AR4420 is the primary metric to monitor for potential short-wave radio interference on the sunlit side of Earth.

    Geomagnetic activity is expected to remain in the quiet range for the next 24 hours, with the Kp-index peaking no higher than 1.3. Solar flare probability remains elevated for M-class events due to the magnetic complexity of AR4420, though X-class potential remains low.

    🌌 Aurora Outlook

    Aurora visibility is restricted to high-latitude polar regions. There is no expectation of mid-latitude aurora displays during this period.

    Monitor the magnetic complexity of AR4420, as any sudden evolution in its spot structure could increase the current 15% probability of an X-class solar flare.
