August 10 2011 Astronomy Newsletter
The Perseids have already started and the peak is expected to be the night of Friday the 12th into the small hours of Saturday morning. The full moon will be a hindrance, but it won’t wipe out the bright meteors.
If you're clouded out, you can still take part. . . .
(1) Live video and web chat Friday night for people in the Americas + European insomniacs. The Marshall Space Flight Center in Alabama will have astronomers answering your questions on August 12/13 from 11.00 - 5.00 EDT. (Java needed) http://www.nasa.gov/connect/chat/perseids_2011.html A live feed to their All Sky camera lets you see meteors that go over the area.
(2) Meteorwatch. They did the Perseids trailer that I sent last week. A meteor map will be recording the observations people tweet to them. You can see their site at http://www.meteorwatch.org/ It was very popular last year. (The site finally crashed at some point.)
(3) Space Weather Radio. The Air Force Space Surveillance Radar tracks satellites and spacecraft - also passing meteors. Stan Nelson has an antenna that picks up the echoes and broadcasts them. Most of what you hear is static, but there’s a noticeable ping or whistle when something is detected. http://www.spaceweatherradio.com/

Now for something completely different. Here is a star trails photograph with a difference. It’s pretty and it made me laugh. The photographer Mike Rosinski had set up the camera and then dozed off.

And here's the latest article from the Astronomy site at BellaOnline.com.
Lyra the Heavenly Harp
Music of the spheres? Here’s a harp to play it on: Lyra, the harp of Orpheus that almost brought his beloved back from death. The constellation has one of the sky’s brightest stars, a star that is really four stars, and a colorful donut.
That's all for now. Wishing you clear skies.
