Total Lunar Eclipse on Sat, 4 April 2015 – Path & Viewing Guide
Global Eclipse Conditions
A total lunar eclipse occurs when the entire Moon passes through Earth's umbral shadow. The eclipse begins with the Moon entering the faint penumbral shadow at 05:03 (GMT-4), though this stage is often difficult to notice. The partial phase starts at 06:17, when a visible dark shadow begins to creep across the lunar surface. Totality begins at 07:53, as the Moon becomes fully immersed in the umbra, often turning a deep red or copper color.The eclipse reaches its peak at 08:00, when the Moon is closest to the center of Earth’s shadow. After that, totality ends at 08:09, and the Moon begins to emerge from the umbra. The partial eclipse concludes at 09:47, followed by a gradual fading of the penumbral shadow until the eclipse ends at 05:03.
