Comet Updates

Comet C/2025 R2 (SWAN) continues to brighten but is still very low in the western sky. It has already passed perihelion and is now on its way out of the solar system. Recent observations put SWAN at magnitude 6.5 to 6.0, probably not visible with the unaided eye, but should be visible in binoculars and small telescopes.

Comet C/2025 A6 (Lemmon) is currently magnitude 6.0, and steadily brightening in the early morning sky. Look for it around 3:00 am in the morning due NE. Follow the three lower stars of the big dipper, and they should direct you to Lemmon, which will be about 10-15 degrees above the horizon. Expectations are still high that Lemmon will reach naked-eye visibility by mid-October. Because of its orbital position Lemmon can be seen both in the early morning hours and early evening hours around 7:00 - 7:30pm.
