(meteorobs) OT -Addendum to Sidhartha.

[Chris Peterson]

Hi Ed-

What's the distance from your camera to the next? Our most productive 
camera pair are about 200 km apart, and these record several 
multistation events per week. Closer cameras catch more than that. Did 
you mean you've never recorded a multistation event, or you've never 
recorded one where you also captured the spectrum?
