(meteorobs) Determining physical dimensions of a largefireballin the sky?

[Chris Peterson]

You should be able to fairly easily calibrate your camera to better than a 
degree in both azimuth and altitude. A tenth of a degree isn't that hard, 
either, and will produce much more useful data. However, if you have only a 
single camera, this calibration isn't too important as you can't extract 
much information from the fireball that requires accurate position.
