Yes, definitely, the G-R—B pattern in SDSS indicates a moving object, because SDSS observed through 5 filters with about a 1-minute lag, in order r-i-u-z-g, and these RGB images use RGB=i,r,g filters.

So, on this picture it’s move from right to left?

r filter = Green is observed first, so I think it’s moving left-to-right.
