Fragmentation
Observation	Yes
Remarks	I saw the fireball dissipate into 3 smaller meteors. The leading most fragment was the largest and the trailing two, were approximately 1/2-1/3 the size of the largest. After the fragments separated, the largest continued on for approximately 1.5 degrees across my field of vision while the smaller two separated and burned up within 1 degree of vision. The two smaller fragments "fell" more in a downward trajectory than the largest fragment. The difference in trajectory may have been 1.5 up to 3 degrees between the largest fragment and the smallest fragment. All were equal brightness and same color spectrum.
