Biggest Supermoon of 2025 Arrives Nov. 5 as Taurids Peak and Comet Lemmon Brightens

With moonlight set to wash out early-month meteors, observers are advised to target darker nights later in November for the best views.

Overview

  • The November full Moon, known as the Beaver Moon, will be the year’s closest and brightest on Nov. 5, marking the center of a rare three-month run of supermoons in October, November and December.
  • NASA data cited by outlets say a supermoon can appear up to about 14% larger and 30% brighter than an average full Moon, though the difference is most noticeable near the horizon.
  • The Southern Taurids reach maximum Nov. 4–5 but will be muted by the full Moon’s glare, while the Northern Taurids peak Nov. 11–12 under darker skies.
  • Comet C/2025 A6 (Lemmon) reaches perihelion on Nov. 8 and could be visible to the naked eye in dark conditions, with better viewing in the Northern Hemisphere early in the month and widening to the south mid‑November.
  • The Leonids are forecast to peak Nov. 17–18 with roughly 15–20 meteors per hour under favorable dark skies just days before the new Moon.
