Dance of the Telescopes

I recently showed this image at an Imaging Group meeting of the Tucson Astronomy Association.
The animation lasts about 45 minutes in real time. Notice the moving shadow of the telescopes, cast by of the moon. The telescopes are at New Mexico Skies, in the Sacramento Mountains, east of Cloudcroft New Mexico.

Ring around the Moon

This image is from the All Sky camera at New Mexico Skies, in New Mexico USA, a wonderful facility with many robotic telescopes. See the message by Steve Coe in the Arizona Observers List.

The Blue Moon Lunar eclipse of December 2009















My good friend Divyadarshan Purohit, with the Planetarium in Vadodara India (north of Mumbai in Gujarat), has sent me images of the eclipse that ended 2009.

See additional images from him at Spaceweather.com page.

"Blue Moon" does not refer to the color of the Moon, but to the rarity of the occurrence of an extra full moon in a season or year.
