How to See the Partial Lunar Eclipse and Blood Moon on August 27
A partial lunar eclipse, often called a blood moon, will occur on August 27, with the best viewing opportunities in the Americas. The event is caused by Earth's atmosphere filtering sunlight, leaving only red wavelengths to illuminate the moon.
Why it matters
Public interest in astronomical events provides educational opportunities for science communication and community engagement.
Earth’s shadow will cover nearly all of the bright lunar disk and will cast a reddish or orange hue on the moon’s surface.
The partial phase will last about three hours and 18 minutes. At its peak, it will have a threshold magnitude of 0.93, meaning that approximately 93 percent of the moon’s diameter will be within the darkest part of Earth’s shadow. Here’s what to expect and how to view it.
