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.

Next 24 h

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.
