A faint blue source is recovered at the SN position, with brightness {m}<SUB>F435W</SUB>=26.76+/- 0.20, {m}<SUB>F555W</SUB>=26.60+/- 0.23 and {m}<SUB>F625W</SUB>=26.32+/- 0.19 mag, although there is no detection in a contemporaneous narrow-band {{H}}α image. The spectral energy distribution of the late-time source is well-fit by a stellar-like spectrum ({log} {T}<SUB>{eff</SUB>}\gt 3.7 and {log} L/{L}<SUB>☉ </SUB>\gt 4), subject to only a small degree of reddening—consistent with that estimated for SN 2006jc itself at early-times. The lack of further outbursts after the explosion of SN 2006jc suggests that the precursor outburst originated from the progenitor. The possibility of the source being a compact host cluster is ruled out on the basis of the source’s faintness; however, the possibility that the late-time source may be an unresolved light echo originating in a shell or sphere of pre-SN dust (within a radius 1 {pc}) is also discussed. Irrespective of the nature of the late-time source, these observations rule out a luminous blue variable as a companion to the progenitor of SN 2006jc.STAMPAenArticle10.3847/1538-4357/833/2/1282-s2.0-85007590833000391169600003https://iopscience.iop.org/article/10.3847/1538-4357/833/2/1282016ApJ...833..128MFIS/05 - ASTRONOMIA E ASTROFISICA
