Fireball report

Reports Report 2635hp (Event 2635-2015)

Observer
Name	K.C. C
Experience Level	2/5
Remarks	I've never seen a falling astronomical object with such an apparent straight-down trajectory. It disappeared behind the houses around me rather than fade into the distance -- it appeared as if it would fall straight into Earth. There was no directional or size change from when I first saw it and when it vanished from view. The time I saw it was pretty general -- I lacked a phone, a watch and scientific fore/afterthought.

Fragmentation
Observation	Yes
Remarks	The fireball appeared to "sparkle" from the nucleus, leaving a short-lived trail just outside the green center. This was visually independent of the tail. Bright orange was flecking out to the sides and being pulled into the tail. The for about one second, as it neared the horizon, the "sparks" were definitely large enough to be distinguished from a generalize orange glow that was the tail. This made the comet appear as though it was a green center inside of a near-halo of orange.
