Waxing Gibbous Moon Glows at 59% Illumination Tonight

Observers can spot major lunar maria unaided, with binoculars or a small scope revealing Mare Nectaris, Alphonsus Crater, and Apollo landing sites.

Overview

  • NASA's Daily Moon Guide lists the phase as waxing gibbous on Feb. 25, with illumination near 59% ahead of a full Moon on March 3.
  • Mare Vaporum, Mare Tranquillitatis, and Mare Serenitatis are easy to pick out without visual aids this evening.
  • Binoculars bring Mare Nectaris and the Alphonsus Crater into view, while a telescope can reveal Rima Ariadaeus and the Apollo 11 and 16 landing areas.
  • The nightly progression has moved from a waxing crescent near 41% on Feb. 23 to a first-quarter Moon around 52% on Feb. 24.
  • Some outlets pair the astronomy with astrology, placing the Moon in Gemini and describing the phase as a time of momentum and decision-making.
