Joy,
You are correct...the brightness, what we call the magnitude does classify a
fireball. A meteor of magnitude -3.0 or brighter is normally considered a
fireball and is archived by both AMS and FIDAC (Fireball Data Center). A
rough guide to how bright this is would be the planet Venus, which would be
a little brighter at -4.0 or so.
Hope this helps!
