Solar flare activity will likely remain limited to occasional C-class events, with the probability for M-class flares currently sitting at 5%.

🌌 Aurora

Aurora visibility is restricted to high-latitude regions.

At Kp 4, observers in far-northern locations such as high-latitude Canada or Scandinavia may witness faint displays, but mid-latitude visibility is not expected.

👁 Watch for

Monitor the magnetic evolution of AR4554 as it rotates toward the center of the disk for any signs of complexity that could elevate flaring probability.
