There was no flash before or after the event, so not an airplane or a star. It was 1:00 am so not a satellite or rocket body.
This camera was supplied to me by the Arecibo Observatory for an upcoming meteor campaign in November. The camera is a Watec 902H Ultimate and it is enclosed in a watec weather proof housing with built in heater to prevent fogging of the lens.
