Moon phase for August 9 enters Waning Crescent stage

On August 9, the Moon is in a Waning Crescent phase with approximately 16% of its surface visible. Observers without visual aids can see the Aristarchus Plateau, while those using telescopes or binoculars may also observe the Grimaldi Basin.

According to NASA, the Moon follows a lunar cycle of roughly 29.5 days, during which its visible illuminated surface changes due to the shifting positions of the Sun, Earth, and Moon. The next Full Moon is scheduled for August 28.
