if not a yellow starburst, then what is it?

z=0.12957,
the object at 01:00 isn't well resolved in DECaLS, but it's there (as blue in the residuals), too close for a random spotPosted

Please put the ID number so I can look it up. Bright blue spots near a nucleus should be examined carefully to see if they are AGN illuminated clouds, or lensed quasars.

The spectrum indicates it is an ordinary galaxy with a mix of blue, yellow and red stars. More red around 7000 so slightly more red stars. No indication of starburst. A big hump would indicate starburst. A hump in blue 4000 would be a recent starburst. A hump in green 50000 would indicate an aging starburst. But there are no humps, so no starburst,.

I'm not sure what the blue area near the nucleus is.
