Partner thought this might have been a firework initially, but the trajectory was all wrong and the way it burned to a peak brightness and then vanished was not like any firework I’ve ever seen.

Remarks
It got brighter and more vivid green as it travelled; the flash was not like an explosion but it definitely peaked in brightness and then quickly vanished into nothing.
