Fairall 51 is a barred spiral galaxy at a distance of D = 64.1 Mpc ([springob_erratum:_2009]; z = 0.0142) hosting an AGN with optical Sy 1.5 classification [veron-cetty_catalogue_2010]. Its extended narrow line region is aligned with the major axis of the galaxy [schmitt_hubble_2003] and shows the same extinction as the broad-line region, indicating dust in the foreground [bennert_size_2006]. The first N-band photometry of Fairall 51 was carried out by [glass_mid-infrared_1982] with the ESO infrared photometer system at the 3 m telescope. Since then, it was observed with Spitzer/IRS in LR staring mode. The MIR spectrum displays silicate 10 and 18 μm emission and PAH emission with a rather flat spectral slope in νFν-space (see also [sargsyan_infrared_2011]). The only subarcsecond MIR observation of Fairall 51 was carried out with T-ReCS in a Q-band filter in 2007 (unpublished, to our knowledge). A compact MIR nucleus was detected without any extended host emission. Our photometry measurement agrees with the flux level of IRS spectrum and thus we use the latter to compute the nuclear 12 μm continuum emission estimate.
