Reports Report 5538ym (Event 5538-2017)

Observer
Name	Alan C
Experience Level	4/5
Remarks	Object seen through thin veil of cloud so no background stars to fix track by. I was in a moving car (front seat) at the time so was unable to hear any sonic effects. Brightness as seen through thin cloud, very bright, similar to brightest iridium flare but moving far to rapidly and while the object seemed brilliant white the trail was distinctly green. For what it's worth I am the planetary section director of the SPA.

Fragmentation
Observation	Yes
Remarks	Just before fading out the object broke into two major pieces and a number of minor ones that faded almost immediately. The two remaining stayed in formation with the smaller slightly below and behind for perhaps 1.5 secs, then the smaller faded with the larger fading straight afterwards; there was no flash just a rapid extinguishing of the light. They were in sight as they faded from visibility, perhaps two thirds of the way to the western horizon and still well above it.
