I initially thought it was the trail of an airplane or helicopter flying through the scene during the long exposure. However, upon closer examination, I think it must be something else, as it strikes me as incredibly coincidental that it would originate dead center from the street light and even more bizarrely, that it would pass in front of the railroad crossing gate and not behind it!
Both prior and subsequent exposures of this scene show no such streak and the rest of the frame looks fine, so I don't think it's the result of any problem with the back ... or at least not a permanent one. (FYI, this was captured with my P30+, clipped from the RAW image processed with the default settings of Capture One v. 6.1, downsized to 1024x768, and then saved as a maximum resolution .jpg.)
I'm well and truly stumped. Does anybody here have any ideas? A secret military project? An anti-photography device built into the streetlight? A robotic firefly?
