    Active Regions
    5
    X-Ray
    A/B (quiet)

    Solar activity remains at quiet geomagnetic levels with a planetary K-index of 1.3, despite moderate flaring activity from the solar disk. Earth’s magnetosphere is undisturbed as we monitor several active regions.

    F10.7 Solar Flux
    151.0
    sfu · >150 = high activity

    The F10.7 solar flux is holding steady at 151.0 sfu, indicating a robust level of solar activity consistent with an active sun. While we recorded minor M-class flare activity from AR4436 within the last few hours, these events have not impacted the geomagnetic environment. Current conditions are classified as R0, with no significant radio blackouts or radiation storms reported.

    Key Metric

    The F10.7 flux at 151.0 sfu is the primary indicator of high solar background activity, sustaining the ionospheric density required for global radio propagation.

    Geomagnetic conditions are expected to remain quiet, with the Kp-index peaking near 2.67 during the next 24 hours. No significant geomagnetic storms are anticipated, and solar flare activity is expected to continue at moderate levels.

    🌌 Aurora Outlook

    Aurora visibility is not expected at mid-latitudes during this period. Observers in high-latitude regions may see standard, quiet-time auroral activity, but conditions are not favorable for lower latitudes.
