RemarksI first saw it as a tiny dot of white/light yellow color from our cockpit, climbing through FL210 (21000 feet with baro set at 1013). Then it became a fireball when it was below our current flight level. The fireball seemed like an explosion of the meteor. I am not certain about the following, this is all I can remember: the initial color in fireball state seemed to be yellow (with orange?) but I also remember a green/blueish color which must have been a few seconds later as the fireball increased in brightness.
Fragmentation
