EclipseTOTAL LUNAR ECLIPSE

Sunday, September 27, 2015
8 PM – 12:30 AM
(Café open 8 – 11:30 PM.)

Members: FREE
Non-Members: Regular Admission

Join us on the evening of Sunday, September 27 for the final total eclipse of the 2014-2015 lunar eclipse tetrad (a group of four consecutive total lunar eclipses)!

The Museum, including the Store, Café, and Observatory (weather permitting), will open at 8 PM and the eclipse will begin at 9:06 PM. The Moon will be totally eclipsed at 10:10 PM and will not begin to leave the Earth’s shadow until 11:23 PM. We will have a live feed from the Observatory into the Theater where Tellus Astronomer David Dundee will describe the eclipse as it happens. Tellus Curator Sarah Timm will also be on hand to talk about our Moon Rock and rocks with similar composition found on Earth.

Last Lunar EclipseIn the Planetarium, there will be special lunar eclipse shows at 8:30 PM, 10:30 PM, and 11:30 PM. Outside, you can view the eclipse through our 20” telescope in the Observatory and members of the Atlanta Astronomy Club will have smaller telescopes set up on the Tellus lawn. If skies over Tellus are cloudy, the Observatory will close and we will stream live images into the Theater from other observatories.

LUNAR ECLIPSE FACTS:
  • A total lunar eclipse can only happen at full Moon when the Moon, Earth, and Sun are exactly lined up. The Earth gets in the way and blocks light from the Sun.
  • At maximum-eclipse, you can still see the Moon with the naked eye. This is because our atmosphere refracts some of the blocked sunlight around the Earth. Longer wavelengths of light, like red light, refract the best, so the moon will turn a deep red color. The shade of red varies by the amount of dust and clouds around the Earth that night.

This event will occur whether the skies are clear or cloudy!
