(meteorobs) Meteor animation and electrophonic sounds

[stange34 at sbcglobal.net]

Karl, In daylight a Oscilloscope can simulate a meteor for the camera if the 
trace dot is set very bright, with a slow or fast sweep speed or triggered 
sweep. Some ambient light shielding might be necessary for contrast. Other 
than that, it would have to be done physically.

I used such a system to evaluate the frame skipping in certain meteor 
software captures.
