Spectral energy distributions of V1647 Ori at five different epochs. Because of the short timescale variability at the optical and near-infared wavelengths, we present photometry from between 2004-02-01 and 2004-04-30 (2004 March), 2004-10-01 and 2004-10-31 (2004 October), 2005-02-01 and 2005-04-30 (2005 March) and 2005-09-03 and 2005-10-03 (2005 September) in these figures. Our models to the SEDs, where the inner radius of the dust disk is set to 0.5 AU in quiescence and 0.7 AU in all outburst epochs, are overplotted with solid lines (see Sect. 4). Between the outburst epochs only the accretion rate was changed here. Note that the model for 2005 September shown here does not fit the MIDI data (see Fig. 5 and Sect. 4.4). The last panel shows all models. The decrease of the brightness of the object with time, from peak (top) to quiescence (bottom) is continuous. References: quiescence − Ábrahám et al.
