Based on unfiltered time-series with a C11 (JD 921.73 - 922.00), 
SDSSJ152419+220920 shows superhumps and 1.5 mag eclipses. Object is at 
mag 15.

I got a good four hour run (JD 921.71 to 921.87) last night using GRAS02 (12
inch located in Mayhill, NM. - 300 second exposures with luminance filter)
It confirms Tom's results. Preliminary analysis shows 1.4 mag eclipses with
a .0637 period.
