Penumbral Lunar Eclipse on Sun, 18 July 2027 – Path & Viewing Guide
Global Eclipse Conditions
A penumbral lunar eclipse occurs when the Moon passes through Earth’s outer penumbral shadow without entering the darker umbra. This type of eclipse is subtle, often going unnoticed unless a large portion of the Moon is shadowed. The eclipse begins at 05:58 (GMT-10), as the Moon enters the penumbra and gradually dims. It reaches its maximum at 06:02, with about 0% of the lunar disk in shadow. The Moon then slowly exits the penumbra, and the eclipse ends at 06:03. No portion of the Moon enters the darker umbral shadow during this event.Local Eclipse Phase Times
