Observation 4- Lunar Eclipse on the Winter Solstice

 Beginning of eclipse: about 1:00 a.m.

 Mid-eclipse: about 2:30-2:50 a.m.
 -Visible reddish hue- about 3:00 a.m.-
End of eclipse- nearly 4:00 a.m.

Total Lunar Eclipse
Location: Pine View
Time: December 21th, 1:00 A.M. - 4:00 A.M.

On December 20th, a total lunar eclipse was visible for nearly three hours. Skies were clear and the visibility of the stars changed as the eclipse progressed. As the full moon entered the Earth's shadow (the penumbra), the light being emitted decreased and more stars came into view. The moon took on a reddish hue during the middle of the eclipse, which is caused by substances in the Earth's atmosphere that obscure the light being reflected off of the moon. The totality of the eclipse lasted for over an hour, which is the longest recent total lunar eclipse. The winter solstice also occurred that morning, meaning that the Sun was at its lowest point in the sky, thus marking the beginning of winter.
