Light curves of V1647 Ori. The vertical dashed lines denote the epochs of the MIDI observations. I_C (0.8 μm) and K_s (2.2 μm) band data are from AP07 and this paper. The I_C data are scaled up by a factor of 40 for the sake of better plotting. 8.0  μm data are from Muzerolle et al. (2005), Paper I, Quanz et al. (2007), this paper (obtained from MIDI acqusition data), and Aspin et al. (2008, extrapolated from their N′ band data). 24  μm data are from this paper and Aspin et al. (2008) (extrapolated from their Q_a band data). 70  μm data are from this paper.
