Mrk 590 is a spiral galaxy at a redshift of z = 0.0264 (D ~ 107 Mpc) with a Sy 1.0 nucleus [veron-cetty_catalogue_2010] and an extended NLR (diameter~ 1.5arcsec ~ 750 pc; PA~-5∘; [schmitt_hubble_2003]) and an unresolved radio core [schmitt_jet_2001]. It belongs to the nine-month BAT AGN sample. Since IRAS, the source was observed in the MIR with the MMT [maiolino_new_1995], with ISO/ISOCAM [ramos_almeida_mid-infrared_2007] and Spitzer/IRS (e.g., [dasyra_high-ionization_2008, weaver_mid-infrared_2010]) and MIPS. Mrk 590 appears compact in the MIPS 24 μm image, while the IRS LR staring mode spectrum shows silicate 10 and 108 μm emission, a weak PAH 11.3 μm feature and an emission peak at ~ 17 μm in νfν-space, i.e., the MIR SED seems AGN dominated. We observed Mrk 590 with VISIR in three narrow N-band filters in 2006 [horst_mid_2008, horst_mid-infrared_2009]. An unresolved MIR nucleus without any sign of host emission was detected in all images. Our reanalysis of the images provides nuclear fluxes consistent with [horst_mid_2008] and the Spitzer spectrophotometry. Note that the MMT and ISO photometric fluxes are ~ 50% higher than the more recent measurements, which is either caused by host emission outside of the central ~ 4arcsec ~ 2 kpc or a decrease of the nuclear flux over the last decade.
