A deep partial lunar eclipse will cover most of the moon's surface on August 27-28 [1].
This celestial event provides a rare opportunity for skywatchers to witness a "blood moon," where the lunar surface takes on a reddish hue. Because the eclipse is nearly total, it offers a more dramatic visual shift than standard partial eclipses.
The phenomenon occurs as the moon passes into the Earth's umbral shadow [4]. This alignment filters sunlight, leaving only the red spectrum to reach the lunar surface [5]. While some reports indicate the eclipse will cover 93 percent of the moon [3], other sources state the coverage will reach 96 percent [1].
Visibility for the event is broad, spanning North America, South America, Africa, Greenland, Iceland, and western Europe [5]. In the U.S., the best viewing conditions are expected in northeastern Colorado, specifically in the region stretching from Fort Morgan to Sterling, Holyoke, and Julesburg [6].
Astronomers and skywatchers are encouraged to monitor local weather conditions to ensure clear skies during the peak of the event [7]. No special equipment is required to view the eclipse, as it is safe to observe with the naked eye.
This event is one of several celestial occurrences this month. Observers in the Western Hemisphere will have a prime vantage point to see the moon's transition into the Earth's shadow before it exits the umbra on August 28 [1].
“The eclipse will cover between 93 and 96 percent of the moon.”
This event is classified as a deep partial eclipse rather than a total lunar eclipse because a small sliver of the moon will remain outside the Earth's darkest shadow. However, the high percentage of coverage means the visual effect will closely mimic a total eclipse, making it a significant event for astronomical study and public engagement in the Western Hemisphere.
