Meteor cameras occasionally record long duration, long pathed meteors that exhibit interesting variations in brightness. At the Winchester Weekend I showed an extreme example that was visible for 10 seconds with a ground track of nearly 500 km, recorded by several video cameras.
Such objects are usually in Earth-grazing paths, skimming the atmosphere and their solar system orbit is such that they are catching up with the Earth, rather than a head-on collision.
I’ll ask the NEMETODE video meteor network if anyone recorded your object. Multi-station captures can give us a ground track and solar system orbit, then we can evaluate the event.
