    UNSETTLED

    Geomagnetic activity is escalating as Earth encounters solar wind disturbances, with a G2 (Moderate) geomagnetic storm likely in the next few hours. Current conditions are unsettled to active, with Kp levels holding at 4.3.

    We expect a peak in geomagnetic activity to Kp 5.67 around 06:00 UTC, reaching G2 storm levels. By 09:00 UTC, conditions are anticipated to settle back toward Kp 4 and stabilize through the remainder of the 24-hour period.

    🌌 Aurora

    Observers at mid-latitudes (40-60°N) should be alert for potential aurora visibility during the 06:00 UTC peak, particularly in regions with low light pollution.

    Those at high latitudes can expect consistent displays as the geomagnetic field remains in an active state.

    👁 Watch for

    Monitor the Kp-index following the 06:00 UTC window to see if the solar wind returns to quiet conditions as forecasted or if the disturbance persists longer than expected.
