That "galaxy with a very bright nucleus" is SDSS J130128.14+275106.6. If you want detailed information about it, go to

this link within the SDSS on-line database

which will show you a close-up image, provide measured magnitudes, AND display
nice spectrum. The nucleus has strong emission lines and a blue continuum rising to
the short-wavelength end. My guess would be an AGN, rather than a starburst
galaxy. The redshift is about 0.24.

(argh! ngc3314 beat me to it, but I _swear_ that I figured all this out myself :-)
