NASA's Daily Moon Guide says the Moon is in a waning gibbous phase on June 1, with 97% of its face still illuminated after the Full Moon.
That slight decline in illumination marks the start of the Moon's slide toward the next New Moon in its roughly 29.5-day orbit around Earth.
Naked-eye viewers can spot Mare Imbrium, Copernicus Crater and Mare Tranquillitatis, while binoculars and telescopes reveal features including Clavius Crater and the Fra Mauro Highlands.
The next Full Moon is due on June 29, as the Moon continues through the eight repeating phases of its monthly cycle.
