The figures
At 08:45 UTC on Sunday, May 31, 2026 the Moon reaches 9°56' Sagittarius with the Sun opposite at 9°56' Gemini. It is 406,136 km away, 21,736 km beyond the 384,400 km average, which puts it at the micromoon end of the range with a correspondingly small disc. The degree, 9°56' Sagittarius, places it in the first decan of Sagittarius, on the axis that runs across to Gemini. It is the second full Moon inside May 2026, which is what the calendar definition of a blue moon means — a quirk of the lunar month being shorter than the calendar one. It is the 11th of the 25 lunations dated for 2026, and the cycle it belongs to is set out in what a lunation is.

Why it is called the Blue Moon
The Blue Moon is the traditional North American and European name for the full Moon of May, and in 2026 it falls on May 31, 2026 at 9°56' Sagittarius. The older alternative is the Flower Moon. Those names follow the calendar month rather than the zodiac, which is why the 2026 one lands in Sagittarius at 9°56' Sagittarius while other years put it elsewhere.
