Penumbral Lunar Eclipse on Fri, 5 May 2023 – 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 05:16 (GMT-10), as the Moon enters the penumbra and gradually dims. It reaches its maximum at 07:25, with about 99% of the lunar disk in shadow. The Moon then slowly exits the penumbra, and the eclipse ends at 09:32. No portion of the Moon enters the darker umbral shadow during this event.Local Eclipse Phase Times
