Overview
- The full Moon reaches maximum illumination at 13:19 UTC on Nov. 5 at roughly 356,980 km from Earth, making it the year’s closest and largest, with an apparent size up to about 14% larger and brightness near 30% higher than average.
- The Southern Taurids peak Nov. 4–5 during the bright full Moon, which will reduce visible rates, while the Northern Taurids (Nov. 11–12) and Leonids (Nov. 17–18) occur under darker conditions.
- Comet C/2025 A6 (Lemmon) reaches perihelion on Nov. 8 and is forecast around magnitude 4–5, potentially visible with binoculars or even unaided under dark, clear skies.
- Observers are advised to view the Moon near rise or set for dramatic perspective, seek dark locations away from light pollution, and allow about 30 minutes for eyes to adapt.
- A visibility index cited by The Action Network ranks Arizona as the best U.S. state to view the Nov. 5 supermoon based on clear skies, low humidity, elevation and access to dark‑sky areas.
