Re: (meteorobs) Fine structure in Leonid stream?

Chris,
            I'll be happy to send you a copy of my tape for 10:00-11:00 UT, as
soon as I can have one dubbed.  I was planning on keeping the original.  I've
been comparing 1-minute intervals from various observers as they've been posted
and most show very strong correlations in the minute-by-minute rise and fall of
rates.  I'm still missing the minute-by-minute rates for at least two seasoned
observers -- here's hoping they'll be sharing their data soon!
