Moon Phase Today: August 2 Lunar Observations
Key features visible on the Moon's surface during its Waning Gibbous phase tonight.
1Today's Moon Phase
According to NASA's daily data, on August 2 the Moon is in its Waning Gibbous phase with 87% of its surface visible. This phase represents the period after Full Moon when the illuminated portion gradually decreases. It's considered the seventh stage in the Moon's 29.5-day cycle around Earth.
2Naked-Eye Observations
The massive dark plain called Oceanus Procellarum (Ocean of Storms), Kepler Crater, and Mare Vaporum (Sea of Vapors) are among the main features visible tonight without special equipment. Some of these formations span hundreds of kilometers and rank among the most prominent on the Moon's near side.
3Viewing with Binoculars
A simple pair of binoculars can reveal Alphonsus Crater's 119km diameter, Mare Humorum (Sea of Moisture), and Mare Frigoris (Sea of Cold) in detail. Alphonsus particularly attracts astronomers' attention with its unusual central peak. These tools provide 10x clearer views of crater edges.
4Telescopic Observations
Telescope users can examine the Apollo 15 landing site at Hadley-Apennine (1971), the 300km-long Rima Ariadaeus fissure, and the unusually oval-shaped Schiller Crater in detail. The Apollo 15 site holds special significance due to equipment left on the lunar surface.
5Lunar Phase Cycle
The Moon's 8 primary phases result from the constantly changing Sun-Earth-Moon angle. The cycle begins with New Moon, progressing through Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter, and Waning Crescent. Each phase lasts approximately 3.7 days.
6Northern Hemisphere Perspective
During Waning Gibbous, the Moon's illuminated portion begins shrinking from the right side for Northern Hemisphere observers. The opposite occurs in the Southern Hemisphere. Phase appearances vary depending on the observer's geographic location.
7Next Full Moon
The next Full Moon on August 28 is also known as the Corn Moon. While not at its closest approach (not a supermoon), it will still present an impressive view with 100% illumination. This late summer celestial event will be visible all night under clear conditions.
8Observation Tips
For optimal Moon viewing, move away from city lights, choose clear nights, and allow 20 minutes for your eyes to adjust to darkness. Since the Waning Gibbous Moon rises around midnight, pre-dawn observations often provide clearer views of surface details as the Moon is higher in the sky.
