The probability of C-class solar flares remains at 60%, suggesting continued minor activity from the existing active regions, while more significant flare events are unlikely.

🌌 Aurora

Aurora visibility is not expected at mid-latitudes.

Observers at very high latitudes may see minor activity, but there is no forecast for significant displays at this time.

👁 Watch for

Monitor the five active regions for any signs of magnetic flux emergence that could increase the probability of M-class solar flares.
