Thanks. I agree that my video results and the video flux data you link 
are in agreement. Interesting that they differ from the visual reports 
(which are plotted on the IMO homepage). I'm guessing that once the 
predicted peak had passed, the visual observations simply slowed down 
(there don't seem to have been many to begin with). One more argument 
for the never sleeping camera! <g>

I do find the double peaked structure interesting. I've never seen much 
structure in the Orionids, and assumed that the debris was quite diffuse 
and uniform. Has anybody modeled the shower this year?
