Has it been seen on more than one image; at the same coordinates? I'm 
thinking of possibilities such as:

 - Propellant or something similar being vented from a satellite.

 - Sun reflections off a satellite.

 - Internal reflection(s) in the telescope/camera.

 - Stray lights eg: street lights, aircraft, torches – especially if they 
illuminate wisps of cloud.
