No major solar radiation storms are anticipated during this period.

🌌 Aurora

Aurora activity will be largely confined to high latitudes.

Observers in northern Canada, Scandinavia, and high-latitude regions may see minor, localized auroral displays, but significant mid-latitude visibility is not expected at this time.

👁 Watch for

Monitor the development of active region AR4513 as it rotates toward the western limb for any signs of magnetic instability that could trigger M-class flaring.
