Survey for z< 0.04 CLAGNs

We use SkyMapper, Pan-STARRS and the Veron-Cetty & Veron catalogue to search the entire sky for these 'changing-look' AGNs (CLAGNs) using a variety of selection methods, where Pan-STARRS has a coverage of 3{pi} steradians (sky north of Declination -30{deg}) and SkyMapper has coverage of ~21000~deg^2^ (sky south of Declination 0{deg}).

We use small aperture photometry to measure how colour and flux have changed over time, where a change may indicate a change in spectral type. Optical colour and flux are used as a proxy for changing H{alpha} equivalent width, while WISE 3.4{mu}m flux is used to look for changes in the hot dust component. We have identified four AGNs with varying spectra selected using our optical colour selection method.
