Camera issue or more interesting?

It only shows up in one r band exposure from 2017-03-24 so it’s probably just an artifact in the CCD, unfortunately. There’s another bright spot in the exposure as well.

Here’s a zoom-in on that one exposure. Unfortunately I think it indeed may be a single-pixel artifact – if it were astronomical, it would have to have a smooth (point spread) profile, but it looks like the central pixel is 2x as bright as the surrounds.
