----
Bolide (as identified by UFOAnalyzer Lyride a) very low in the west probably alrgo the coast of France.
In my shot the fireball disappears behind a building when it is still the most (so far) of its brightness, that given the low altitude at the time of his death behind the building (only 4 degrees altitude ) Should have been spectacular when viewed from closer.
