Abstract:                                ! Free format text (please update)
    In an earlier G270H spectrum, we discovered an apparent broad
    MgII line in the prototypical powerful double radio galaxy
    Cygnus A, showing that the latter harbors a hidden quasar.
    Because of low SNR and an unflagged bad diode in the FOS/BL array
    at the redshifted MgII line, this result needs to be confirmed.

     Observing_Description:
         We already have a spectrum under virtually identical
         conditions (Fig. 1), so it's reliable to go by that. The
         throughputs are a little lower now, but less of the
         (spatially extended) target will be outside the observing
         aperture with Costar. These are compensating (\ltwid 20\%)
         effects. 
         Our target is spatially extended and complex, so
         we will use an offset star accurately measured at 2.4 * 10^-15
         ergs/cm^2sAngstrom\ on our FOC image (GASP v=12.2).
