    Geomagnetic conditions are currently settling after a brief, heightened period of activity. While the Kp-index reached G2 levels early today, the environment is trending back toward quiet to unsettled levels for the remainder of the forecast period.

    The planetary K-index has dropped to 2.3 as the recent geomagnetic perturbation wanes. Solar activity remains moderate with an F10.7 flux of 127 sfu and four active regions currently on the solar disk. X-ray flux is quiet, with only minor C-class flaring detected over the past 12 hours.

    Key Metric

    The 24-hour Kp forecast is the primary indicator, as it confirms the transition from a short-lived G2 event back to minor, background-level geomagnetic conditions.

    Geomagnetic activity is expected to decline further, dropping from Kp 4.0 toward Kp 3.0 within the next six hours. Conditions will likely stabilize at unsettled levels for the rest of the day, with no significant solar radiation storms anticipated.

    🌌 Aurora Outlook

    Aurora visibility is currently limited to high-latitude regions. As the Kp-index continues its downward trend, the likelihood of auroral displays at mid-latitudes will diminish rapidly throughout the day.

    Monitor the stability of AR4435 as it approaches the solar limb; while current flaring is limited, its magnetic complexity warrants routine oversight.
