Re: (meteorobs) ZHR of meteor showers II



Hi,

Yes Michael , I have been discussing this strange observation as regards to 
the ZHR calculated . I guess that the Method which IMO uses is the one 
using the magnitude distribution could hopefully solve the problem . I have 
calculated it using Metshow , which does not take into account the 
magnitude distribution .

The thing is that all the observers below are mostly experienced observers 
who have been observing for more then 10 years in most cases.



If anyone has any suggestion or comment they are most welcome to send it!

Martin
