Nice find!
It is the right colour for a supernova. Nothing in SDSS. Nothing in NED.
I can't see the blue/green separation typical of an asteroid. There is a slight chance that the image was taken when the asteroid wasn't "moving", eg just before retrograde motion. Let me look for another asteroid nearby. No, a nearby asteroid shows the normal blue/green colour http://legacysurvey.org/viewer?ra=172.8161&dec=2.0933&zoom=16&layer=decals-dr2

Previously seen it, but SN could be ruled out after checking absence in g-band.
Please double check again and consider a cosmic ray hit (squared green spot) 😃

Ok, too green to be a supernova. Thank you c_cld.

Thanks. Thought it was a bit to green but you never know at least I don't, but I have to ask to make sure.
