The fireball seemed to just come apart as it approached the horizon, breaking up into blue-green-white flashes like a cheap roman candle misfired.
Fragmentation
Observation
Yes
Remarks
As the fireball came apart, there were flashes of blue and green and pieces of it separated in multiple directions and then these smaller pieces which glowed white and continued their fall at a sharper angle until they either dissipated or disappeared from my field of vision which was limited to a deciduous tree line.
