(meteorobs) shower activity in the past

[Mikhail Maslov]

Hello.
I'm interested in data concerning activity of different showers in the
past, but not only the years of ununsual activity, but also ordinary
years. Say, for Leonids and Draconids there are much information
about heightened activity, but ideally I wish to know activity
profiles or maximum rates in ordinary years, even if these rates were
about zero. Are there in the Internet any information on this matter?
Thanks in advance, Mikhail Maslov
