Upper panel: optical spectra of WISE J235612.70+403646.8, counterpart associated with the BZB 2FGL J2356.1+4034 classified by Ackermann et al. (2011a). In our observation its spectrum appears as that of a normal elliptical galaxy lying at redshift 0.131 instead of 0.331, as previously reported in Ackermann et al. (2011a). 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 potential counterpart of 2FGL J2356.1+4034 is indicated by the red circle.
