[vsnet-campaign-dn 1268] WZ Sge
How interesting! The U-band light curve from 010816
differs remarkably from the 010815 light curve. You
can see the two curves at

where 'd' refers to the 4th night of NOFS U-band photometry.
010815 was quite chaotic; 010816 is quite regular with
single peak and nice eclipse.
Note that the companion to WZ Sge is quite red, and
is already starting to affect the photometry at the 0.1mag
level if you are doing unfiltered photometry and using
an aperture large enough to include both stars.
