How to determine if a new object in the sky appeared?

Hi all,

tonight I was taking some 60 sec long exposures with a fisheye to catch some meteors and in one frame a very bright spot appeared in Sagitta's area. It was not present in the previous nor in the next frame and looking at a star chart, it looks there is no known object in that area so I guess it is an artifact but better to ask, I think.
Attached the frame with some references to identify the area. Unfortunately, as I was just chasing some meteors, I didn't put the time stamp on the frame but it was taken at around 20.00 UTC
