Pardon the repost, but this was buried in another message last time:

To Neil, George, Bob, Mark, Norm, and all other experienced observers:

According to some variable star literature I've read, the eye's sensitivity to 
brightness changes is very dependent on the color of the light. Red variables 
with certain amplitudes will appear to vary MORE than blue variables with the 
same mag and amplitude, by as much as 1 apparent magnitude's difference.

This is in addition to the well-known illusion which makes a red star of V=1 
appear brighter than a blue star of V=1.

Surely, then, the *perceived* color of a meteor should be taken into account in 
magnitude studies, not to mention when one is noting variable-brightness (e.g., 
flaring) meteors. Thoughts from anyone about this?
