<< Teff -------- .92 >> Good work Jonathan! One thing you might want to keep in mind is that IMO and NAMN like to see a minimum of 1 hour observing period. All you have to do is keep track of how long it takes to record each meteor. For example if it takes 1 minute to record each meteor and you see 5 meteors that night to get a 1 hour Teff you need to actually observe for 1 hour and 5 minutes, OK? Keep up the good work. Kevin
