So Simbad says one of the objects is " SDSS J032009.02-061549.2 – Object of unknown nature". Using the viewer, I’m trying to locate what object is being referenced – it’s difficult to tell. What object is “unknown”?
in the finding chart you will see that the cyan marker is not on the center of the galaxy – what has happened is the SDSS software has split that galaxy into multiple components, and Simbad doesn’t know what this component is. (It’s a galaxy.)
