WASHINGTON, Aug. 21 (UPI) — People across the western United States will have the best opportunity early Aug. 28 to witness the longest lunar eclipse in seven years.

During the early morning hours of Aug. 28, astronomers say sky watchers around much of the world will be able to watch as the moon crosses the Earth’s shadow, becoming completely immersed for nearly 90 minutes — a much longer period of time than occurs during most lunar eclipses.

The National Aeronautics and Space Administration said the event will begin 3:54 a.m. EDT, Aug. 28.

The eclipse will be visible from Australia, parts of Asia and most of the Americas but not from Africa or Europe, NASA astronomers said.

The view is different from each location. In the United States, Pacific observers, including people in Hawaii, are favored with the entire event visible in the post-midnight sky. However, along the East Coast and in the Great Lakes area, totality will be cut off early by sunrise.
