This is what I currently do here in the warmer climates of S. Carolina. But
when I lived in the Blue Ridge Mtns. of Virginia, the cold would kill my
batteries even covered up!

Your color perception is definitely greater than mine as your percentages
are a lot higher. Also, I have never seen color in a +3 mag or fainter
meteor and color in only a small percentage of +2 mags (probably related to
my vision). Of the +3 magnitude and fainter class, have you been able to
determine whether one color predominates over the others?

This book was written by Ernest J. Opik, published in 1958 by Interscience
Publishers. Another good book, but definitely math-intensive.
