(meteorobs) Re: Trains and Magnitudes
Kim,
I'm certain that swift meteors of all magnitudes produce trains. It's
just difficult for the eye to see the fainter ones. I have seen trains
on meteors as faint as 4th magnitude. I'm sure Norman McLeod has seen
trains on meteors fainter than that. I'm sure it depends on one's visual
acuity.
Clear Skies!
