The Close AGN Reference Survey (CARS) - Mrk 1018 returns to the shadows
  after 30 years as a Seyfert 1
  We report the discovery that the known `changing look' AGN Mrk 1018 has
changed spectral type for a second time. New VLT-MUSE data taken in 2015 as
part of the Close AGN Reference Survey (CARS) shows that the AGN has returned
to its original Seyfert 1.9 classification. The CARS sample is selected to
contain only bright type 1 AGN, but Mrk 1018's broad emission lines and
continuum, typical of type 1 AGN, have almost entirely disappeared. We use
spectral fitting of the MUSE spectrum and previously available spectra to
determine the drop in broad line flux and the Balmer decrement. We find that
the broad line flux has decreased by a factor of 4.75+/- 0.5 in H{\alpha} since
an SDSS spectrum was taken in 2000. The Balmer decrement has not changed
significantly implying no enhanced reddening with time, but the remaining broad
lines are more asymmetric than those present in the type 1 phase. We posit that
the change is due to an intrinsic drop in flux from the accretion disk rather
than variable extinction or a tidal disruption event.
