Red blotch on left galaxy

• by Ghost_Sheep_SWR

  What is the red blotch atop the multi-coloured galaxy to the left? It is visible in both DECaLS and SDSS.

  Sharp edges, looks like a cosmic ray hit.

  Thought so too, and wouldn't have flagged it but for the same thing(s) seems to be showing up in the DECaLS SDSS imaging. (Actually two blotches).

  EDIT Image DECaLS SDSS image

  What DR of SDSS is DECaLS using btw?
