DECaLS only interesting object

Red object.


Really red objects can either be because they’re actually intrinsically red – for example, high-redshift galaxies, or cool brown dwarf stars. Or they can be transient objects that are only observed in our z-band image (mapped to red in these images).

I believe this one might be the asteroid “2104 T-2”, observed 2013-11-22 @ 02:51:12.5.
