(meteorobs) Re: Opik

Hello Chris, Rob and everybody,

This discussion seems interesting, and I have a question :

what to think of reported ZHR=~ 50000 in 1833 (Brown 1999, Icarus 138) ??

Does this contradiction comes from the fact that this rate is deduced from a duration of observation of only 15 min maximum ?
Actually, I do not knonw the Opik method (and books seem hard to find...) : is it easy explicable ? Thanks.
