🌍 About This Eclipse

A total lunar eclipse occurs when the Earth passes directly between the Sun and the Moon, causing the Earth's shadow to completely cover the Moon. During a total lunar eclipse, the Moon can take on a reddish color due to the scattering of sunlight through the Earth's atmosphere, often referred to as a "Blood Moon."

A lunar eclipse is a geocentric event. The contacts and magnitudes on this page are the same for every observer who can see the Moon at that moment.
