    sfu · >150 = high activity

    The solar disk features six active regions, but they are relatively stable with minimal flare production. The current Kp index is at a nominal 2.0, reflecting stable conditions in Earth’s magnetosphere. Radio flux is measured at 122 sfu, indicating moderate solar cycle progression without anomalous intensity.

    Key Metric

    The current Kp index of 2.0 indicates a stable geomagnetic environment with no significant impact on satellite operations or power grids.

    Expect geomagnetic conditions to remain in the G0 category, with the Kp index likely to fluctuate near 3.0 by late today. Flare activity will remain low, with a 90% probability of C-class flares but only a 40% chance of M-class activity.

    🌌 Aurora Outlook

    Aurora visibility is not expected at mid-latitudes. Observers in high-latitude regions may see minor activity, but there is no potential for sub-auroral displays at this time.
