Moon Enters Third Quarter on August 6, 2026

On Thursday, August 6 2026, the Moon reached the Third (Last) Quarter phase, with roughly 45‑48 % of its surface illuminated. NASA’s Daily Moon Guide notes that the left half of the Moon is lit, marking the waning stage between the Full Moon and New Moon.

Observers in the Northern Hemisphere can spot features such as the Oceanus Procellarum, Copernicus and Tycho craters with the naked eye, while binoculars reveal Gassendi, Clavius and Mare Humorum. Telescopes can show the Schiller crater and Fra Mauro Highlands. The next Full Moon is expected on August 28, 2026.
