Has anybody got any idea what that dark blue fragmented line beside the centre galaxy is?

It could be a satellite trail (or that of a high-flying aircraft), or it could be the diffraction spike of a bright star waaay off-stage. It could also be an artifact of a different kind (I'm not very familiar with artifacts produced by the UKIDSS camera).
