Overview
- The Buck Moon reached peak illumination on Wednesday, July 29 at about 10:36–10:37 a.m. Eastern time, though observers saw it appear full at local moonrise that evening.
- Skywatchers were advised to view the moon shortly after sunset near a low, dark horizon where the rising lunar disk looks largest and shows an orange tint.
- Rayleigh scattering explains the orange appearance at the horizon and Canadian wildfire smoke further intensified orange hues in parts of the U.S. Midwest and Northeast.
- The full moon rose near Saturn, Mars and Mercury in a compact summer lineup and its bright face reduces visibility of faint meteors from showers active now.
- The Buck Moon precedes an Aug. 12 total solar eclipse and an Aug. 27–28 deep partial lunar eclipse, and it coincided this year on the calendar with India’s Guru Purnima.
