(meteorobs) Definition of "seeing"
I keep using a term "seeing" which I thought was sort of a technical
term. In my distant past we would speak of "seeing" as so many arc
seconds, which is the size of a star image that one would see in a
telescope and was assumed to be a measure of the atmosphere's
stability. What brings this to my mind is that the improved LM in my
back yard last night I think was due to the good "Seeing".
