Composition of the metorite and the air it's hitting is what I was told, along with the temp of the object. <br><br>Went out shortly after 0330 and stayed out for an hour and a half, when clouds started moving in and reflecting too much of the light from in town (was screeened by trees while it was clear out). Stopped counting at 35 in 15 minutes. <br><br>Had 3 fireballs that I saw, and 4 more that came in "behind" me- very, very bright. Moslty white, mostly dim, but had a lot of greens and a single red, though one of the other amature astronomers I know thought it might have been unrealted the shower, based off the angle. <br><br>Until the clouds moved in, Vermont had excellent veiwing conditions. Almost no clouds, and so long as you were screened from town lights, increadable clarity. Also took the time to do some looking at Jupiter and some of the other nice things through binocs.
