Oct 30 Jeweled Handle visible on Moon
From AI- The Jeweled Handle (or Golden Handle) on the Moon is a clair-obscur effect where the peaks of the Montes Jura mountain range, bordering the Sinus Iridum (Bay of Rainbows), are illuminated by the rising sun at lunar dawn. This creates the illusion of a "handle" formed by bright, curved mountain peaks against the shadowed basin of the Sinus Iridum.

Look out for:

Comet C2025 R2 SWAN

C/2025 A6 Lemmon
