Wot's this one called, then?

Anyone able to help me identify this object?

Parts of the trail showed up on three adjacent 30 second subs at 00:29 and 00:30. This is the middle one (unprocessed apart from size reduction and conversion to jepg) and the trail should be 30 second worth of movement. The central (very) faint fuzzy is NGC 6946 (Fireworks galaxy).

Can't find a nearby satellite on my admittedly fairly elderly version of Stellarium but assume that's what this is?

First thought was a meteor but they don't last that long (usually).

I think if the narrow trail continues to the edge of the frame in the preceding and succeeding frames then my guess would be a satellite that briefly catches the Sun on a surface large enough to see from your location.  Kind of like an Iridium flare, but on a smaller scale.

Thanks Gina and James.

I thought satellite, but couldn't find a suitable candidate - operator probably!

Maybe it's something hush-hush if you're finding it hard to source info
