over-enhanced pixel: computer processing artifact that looks like a star
In a previous chat, we very slightly debated a blue spot as a star or artifact, and I mentioned I'd seena clear example, and saved it. This is the image. The green spot does not appear on the large skyServer image, and is slightly enhanced on the View on SkyServer page, but aas presented to us ZooPeople, is hugely enhanced.
So I just wanted to share this unusual artifact. It is not a star, but a result of the software program, is my bet.
It is only visible in the 'r band, so it is a artifact. I would say particle strike is a likely cause.
