dc.descriptionWe discuss the signatures of an evolving accretion disk around the nucleus of NGC 1097, based on observations of its double-peaked H-alpha emission-line profile which cover a time span of 10 yrs. The monitoring of the profile has allowed us to better constrain the inner radius of the accretion disk, and to propose a scenario in which the ionizing source is getting dimmer and making the peak of the disk emissivity to drift inwards.
