Re: (meteorobs) sporadic cycles
Just a thought to throw out that has been rolling around in my
brain......always a dangerous thing.
I think I've noticed the sporadic cycle correlates very well with the
number of shower members expected at any given time- i.e. the large number
of minor showers (as well as major)during the late summer. This has caused
me to wonder if perhaps this sporadic cycle is just a manifestaion of
shower members not being assigned to these minor showers. Equally true
could be the converse...perhaps some of the minor showers we chase are
nothing but the scattering of higher sporadic counts, leading to a myriad
of "minor" showers. I'm not saying either one is the case, as I'm certainly
no expert, but I thought I'd throw this out for comment. I will now duck,
and don my asbestos underwear while we discuss. Have a go guys.

That's my observation too.

Again I've found the same for telescopic meteors.
