I have watched a number of meteor showers in my life. Most observations I have made seem to take place at elevations similar to satellites like the international space station. The fireball we saw in phoenix appeared to be at a much lower altitude. I think it is the largest fireball I have seen.
It was similar in color and consistency to watching a child playing with a sparkler on the fourth of july. The sparks emmitting were fading away near the fireball.
