Lunar Eclipse Tonight
Tonight across the Yucatan Peninsula (weather providing) stargazers will be treated to one of nature’s great celestial shows, a Lunar Eclipse.
Slated to take place at approximately 18:50 Central Time, and to last almost 4 hours, the eclipse will be one sure to excite and challenge the amateur astronomer.
The type of eclipse that will be occurring is a penumbral Eclipse – an eclipse that occurs as many as 9 times per century on average.
This is where the moon passes through the penumbra of the Earth, causing a “slight” darkening of the moon.
It is a narrow path for the moon to pass within the penumbra and outside the umbra. It can happen on the Earth’s northern or southern penumbral edges.
In addition size of the penumbral is sometimes too small to contain the moon.
