Where the satellites are...

Check this out.

A window will pop up and ask you if you want to run it. Click yes. You will get a real-time display of all the satellites orbiting the earth. The ring of satellites is the ones in geosynchronous orbit - they stay in the same place in the sky so that you can aim your DirectTV dish once and then forget about it.

You can zoom in and out on the earth and roll it around to find where you are at. Of greater interest is that you can click on a satellite and see its orbit. If you happen to be out shortly after sundown or just before sunup, you can look to see if you can watch a flyover. This is when the sky will be dark, but the satellite will still be illuminated by direct sunlight. It's very cool to watch.

Anyway, it's a cute program and I like to fire it up from time to time.
