Bitten Moon: August 27, 2026 Partial Lunar Eclipse Feeds a Bright Rim, Not a Red Disk
A deep partial lunar eclipse on August 27–28, 2026 will see about 93% of the Moon’s diameter enter Earth’s umbra, producing a striking “bitten” look as a bright rim remains visible rather than a red Moon. The 96% figure you may see refers to area, not width, and the Moon never reaches totality (greatest eclipse around 04:13 UTC). This event is one of the deepest partial eclipses of 2021–2030, not a blood Moon, and the Danjon brightness scale doesn’t apply here. Timing for observers varies by location, with Americas facing the deepest phase at night on the 27th; the next total lunar eclipse won’t occur until June 26, 2029.
