Dip the light curve fo V485 Cen?
 
Observations of V485 Cen from May 16/17 to May 23/24 made with 1.3-m
Warsaw telescope at Las Campanas Observatory show linear decrease of
brightness of the star with rate of 0.1 mag/day. Data collected on the
last night (May 24/25) showed rapid change of the rate of decline. In
comparison with the night of May 23/24 the star faded over 0.5 mag.
Is this the a begnining of a dip observed during superoutburst of some
WZ Sge stars, or rapid end of the superoutburst?
