(meteorobs) Re: Geminids time of maximum against magnitude

They have.  There was a paper (Fox et al. 1983 I think) which claimed
that the Geminids might soon be on the decline.

This also talks about the mass segregation.

There is a classic BAA paper by George Spalding looking at the time of
maximum against brightness.

Both radar

and telescopic data (sorry can't lay my hands on the reference where
this is reported at the moment) have shown that the fainter meteors peak
earlier than the bright ones.  There are a number of effects that cause
this mass segregation.  See Jim Jones's paper

and another by Duncan Steel.

No doubt there have been more recent studies, but I think the above
papers is where the 20-year recollection mentioned already arose.
