Winter Solstice Total Lunar Eclipse


Not since 1638 has a total lunar eclipse coincided with the Winter Solstice. Tuesday Dec. 21 is our shortest day of the year – the beginning of winter. Between Monday night and Tuesday morning the earth’s shadow will totally engulf the Moon from 2:41AM to 3:53AM EST. Unlike a solar eclipse, it is safe to view a lunar eclipse with the naked eye or binoculars, both work well. All it takes is a good alarm clock and a clear sky. For the 72 minutes of totality, you will notice a second deeper night. Stars that were hidden by moonshine will appear. The moon may take on a reddish glow. This is the result of the reflection onto the moon from the ring of Earth’s sunrises and sunset. The Earth’s atmospheric conditions really are the key to the eclipse’s color. Only on rare occasions will the Moon go black. The next total lunar eclipse to appear in our area is not until April 14-15 2014.
