February 20 Lunar Eclipse

These aren’t much, but I’m no photographer either.

For awhile we had good visibility of last night’s lunar eclipse here in southern Nevada. Ian and I went back in to get some coats at about 6:20 pm (PST -0800UT) and got distracted by some dog vs. cat shenanigans. When we got back outside about 6:45 pm, the then partial eclipse was obscured by cloud cover moving in from the east-southeast. The sky is still overcast as I write this the next day. Oh well.

This is a crop from that picture showing the Earth’s shadow (the Penumbra) on the Moon.

Geminid Meteor Shower Peak Dec. 13, 2007

Saw this over at Follow Me Here and knew I had to pass it along. Thanks, Eliot.

Best Meteor Shower of 2007 [Yahoo! News]
Geminids Peak Dec. 13: “If you have not seen a mighty Geminid fireball arcing gracefully across an expanse of sky, then you have not seen a meteor.

…Studies of past find the “Gems” have a reputation for being rich both in slow, bright, graceful meteors and fireballs as well as faint meteors, with relatively fewer objects of medium brightness.

…Geminids also stand apart from the other meteor showers in that they seem to have been spawned not by a comet, but by 3200 Phaethon, an Earth-crossing asteroid. Then again, the Geminids may be comet debris after all, for some astronomers consider Phaethon to really be the dead nucleus of a burned-out comet that somehow got trapped into an unusually tight orbit. Interestingly, on December 10, Phaethon will be passing about 11 million miles (18 million kilometers) from Earth, its closest approach since its discovery in 1983.

The Geminids perform excellently in any year, but British meteor astronomer, Alastair McBeath, has categorized 2007 as a ‘great year.'”
