IM Nor light curve. Both panels are folded on the 0.1026-day period. The top panel is taken from Woudt & Warner (2003) and shows the IM Nor on four nights from JD 2452696−2452701 in the tail of the eruption. The bottom panel is a running average of the unfiltered CCD magnitudes of Monard from JD 2453179 in quiescence. We see a broad dip, which is too broad to be from an eclipse alone. Woudt & Warner interpret the dip as being primarily a reflection effect from the inside face of the companion star plus a partial eclipse of the accretion disk. The folded light curve is essentially identical between the two panels, despite the change in irradiation from eruption to quiescence.
