I separated the times into smaller intervals than an hour so
that a lull could be seen from 7:20 - 7:29. There was a definite change in
the meteors at that time. Before the lull in that interval, there were
several bright Leonid meteors that looked orange-red with a dark center
(almost black). One lasted 7 full seconds before burning out well back
behind us! After that, the meteors changed color! No bright meteors were
orange after that, but instead had a bluish cast. Some grey-blue, others a
sort of green-blue (but not the aqua color of many fireballs in 1998). It
was almost as if we entered a different stream of meteors. I hope others
that watched at these times can verify.
Unfortunately, I was unable to see the maximum due to clouds
that came in after this. A bitter disappointment.
