Well, you might notice the part of my reply in quotes...had to look that up for a concise description...I did take a year of advanced physics in college, but, oc, that was a loooong time ago. Studied some celestial navigation when I went cruising, but that sort of fell by the wayside, w/GPS.

Guess you don't see too many green flashes in Nebraska.
