    QUIET

    Current solar conditions are quiet with the planetary K-index at 1.3. While geomagnetic activity is minimal, the solar radio flux remains high at 190 sfu, indicating a robust solar cycle.

    Expect a minor uptick in geomagnetic activity reaching Kp 3.3 during the next 6-12 hours, remaining well within quiet levels.

    more

    No significant storming is anticipated, and solar flare activity is expected to remain largely limited to minor C-class events.

    🌌 Aurora

    Aurora visibility is not expected at mid-latitudes.

    more

    The current Kp index is insufficient to push the auroral oval beyond high-latitude regions, making observation unlikely for those outside of polar latitudes.

    👁 Watch for

    Monitor the development of the five currently identified active regions for any rapid magnetic growth that could increase the probability of M-class flares.
