Vagabonds from space visit the inner solar system!
Here's What's Up!
The holiday comet is here at last. Comet C/2012 S1 (ISON), the new sun grazing comet was discovered on September 21, 2012 by Artyom Novichonok and Vitali Nevski, using a 16-inch telescope that is part of the International Scientific Optical Network (ISON). Its nicknamed the Holiday comet because its perihelion date is November 28, Thanksgiving Day in the U.S. and it is expected to return to the night sky in time for Christmas, 2 weeks later.

NASA Comet ISON Observing Campaign
Comet ISON comes to Life - John Bortle reports from Sky & Telescope also provides charts
Until perihelion the comet is in the morning sky and currently can be seen in binoculars. Look near Spica and Mercury. The Minor Planet Center also provides empherides that can be imported into your planetarium programs and telescope pointing programs. This includes Astra's favorite open source planetarium program Stellarium.

Great Comets that shone during the Age of Information:
Comet 2006P/1 McNaught
The brightest comet of the new millenium so far! C/2006 P1 a.ka. Comet McNaught
Discovered by Robert McNaught of the Siding Spring Observatory in Australia on August 7, 2006. Perihelion was January 12, 2007.
Peak magnitude estimate -0.6! So long, Comet McNaught, it won't be back to visit the inner solar system again.
Comet 73P/Schwassmann-Wachmann 3
In 1995, Comet 73P/Schwassmann-Wachmann 3 split into "mini-comets" flying single file through space, much like Shoemaker/Levy9 that crashed into Jupiter. Closest approach to Earth: 5 million miles on May 15, 2006.
Old comets never die, they merely fade....
OR crash into planets....OR break up into pieces....OR hit the sun...Or are flung out of the solar system never to return

Well, 1986 was a bit before the age of information, wasn't it???
What's the fuss?
