Star Party: Total Lunar Eclipse Viewing

Jan 20 | 7:00PM

The January 20th Full Moon will have its own special show, a total lunar eclipse! The Full Moon will slide through the dark shadow of the Earth, and for 62 minutes the only light hitting the Moon will be the reddish glow from Earth's sunrises and sunsets resulting in a total lunar eclipse. 

The first contact of the partial eclipse starts at 7:33 p.m.. The eclipse’s total phase will last for 62 minutes, beginning at 8:41 p.m.. The point of the greatest eclipse will occur at 9:12 p.m.. The eclipse ends at 9:43 p.m.. The eclipsed moon will be 43 degrees above the southeastern horizon at the instant of the greatest eclipse. Finally, the partial eclipse ends at 10:50 p.m.. 

Unlike solar eclipses in which the Sun's rays can damage the eyes, lunar eclipses are safe to watch with the naked eye. Lunar eclipses are unique in that no one can predict what color the Moon will turn during totality. Binoculars and telescopes will enhance the view.
