July's Buck Moon Reaches Full Illumination at 10:36 a.m. EDT on July 29

Summary

  • The July full moon peaks at 10:36 a.m. EDT on July 29, marking the first full moon of summer and appearing fully lit opposite the sun.
  • Sunset on July 29 offers the best viewing, with the moon rising in the east near Capricornus and often seeming unusually large and yellow-orange near the horizon.
  • That oversized look comes from the Moon Illusion, while the warmer color is caused by Rayleigh scattering filtering out more blue light through Earth's atmosphere.
  • Buck Moon is one of several traditional July names tied to seasonal change, alongside Raspberry Moon, Thunder Moon and Hay Moon, and the date also aligns with Guru Purnima and Asalha Puja.
  • Moonlight will wash out fainter sky objects, but viewers can still spot the Summer Triangle, Antares, Venus after sunset, and Saturn, Mercury and Mars before dawn.
