NASA Reports Waning Gibbous Moon Phase With 93% Visibility
NASA's Daily Moon Guide indicates the Moon is in the waning gibbous phase with 93 percent visibility. Observers can view specific lunar landmarks, including craters and maria, using varying levels of magnification ranging from unaided vision to telescopes. This current stage is part of the Moon's regular twenty-nine-and-a-half-day cycle governed by its orbital position relative to the Earth and Sun.
Key points
- NASA's Daily Moon Guide reports the Moon is in a waning gibbous phase with 93% of its surface visible.
- Observers can view features like Mare Tranquillitatis, Copernicus Crater, and Tycho Crater without visual aids.
- Binoculars allow visibility of the Alphonsus, Endymion, and Clavius craters, while telescopes reveal the Apollo 14 landing spot, Rupes Altai, and Linne Crater.
- The Moon completes its full cycle of eight phases approximately every 29.5 days as the sunlit angle shifts relative to Earth.
According to NASA's Daily Moon Guide, the lunar cycle has progressed into the waning gibbous phase, featuring ninety-three percent surface visibility. Observers looking up without equipment can identify major lunar landmarks such as the Mare Tranquillitatis, alongside the prominent Copernicus and Tycho craters.
For those utilizing supplementary viewing equipment, binoculars aid in spotting the Alphonsus, Endymion, and Clavius craters. Telescopes provide even sharper clarity, bringing the Apollo 14 landing site, Rupes Altai, and Linne Crater into view.
NASA explains that the lunar cycle encompasses eight distinct phases, repeating roughly every twenty-nine and a half days. These visual changes occur due to the shifting geometric angles between the Sun, Earth, and Moon as it orbits our planet.
