Upper panel: optical spectra of the Fermi source: BZB J0650+2503 listed in the Roma-BZCAT v4.1. Our observation clearly shows a featureless continuum and allows us to confirm its classification, but unfortunately, we were unable to confirm the redshift estimate reported in the Roma-BZCAT. The average S/N is also indicated. Middle panel: normalized spectrum. Lower panel: 5′ × 5′ finding chart from the Digital Sky Survey (red filter). The source is indicated by the red circle.
