When is the next supermoon?
The next one in this calendar falls on Tue, 24 Nov 2026. Its exact full-Moon instant is 24 November 2026 at 14:54 GMT.
The distance rule used here
Supermoon is a popular term, not an official phase. This almanac marks an exact full Moon as a supermoon when its direct geocentric distance is no more than 361,400 kilometres. A fixed 360,000 km rule is stricter. The original Nolle convention uses 90% of the distance span between selected perigee and apogee; this page uses the explicit 361,400 km cutoff consistently. Other published rules can produce a different list.
The Moon's orbit is elliptical, so its distance changes continuously. A nearby full Moon can look modestly larger and brighter than a distant one, but foreground scale and atmospheric colour often make the visual impression more dramatic.

A micromoon at 405,000 km has about 29.5′ apparent diameter; a Moon at 361,400 km spans about 33.1′, roughly 12% larger across the disc.
Observing from the UK
Exact full-Moon time is useful for the almanac, but weather and horizon access matter more in the field. Check the evening before and after, choose an open eastern horizon near moonrise, and use a landmark if you want the apparent scale to read in a photograph.
