(meteorobs) Plotting chart wanted for Levy comet/radiant

[John Drummond]

Hi again,

thanks for the info and links that various people posted. I only got to look 
at the August Pavonids/Indids on two nights and I observed the following:

Friday 31 Aug = 2 shower
Saturday 1 Sept = 1 shower

Sorry I can't give the sporadic counts as I plan to play my observation 
tape/record the data this weekend...

David Levy and I thank to everyone who helped.

Cheers

John Drummond
