Hi CBAers,

This one definitely looks worth following!  Full info on it is contained 
on the Catalina Sky Survey CV page:
nessi.cacr.caltech.edu/catalina/BrightCV.html

Superhump observations at this long a period are somewhat rare (because 
the stars are, not because they don't superhump) - so that gives it a 
higher importance.

    Colin Littlefield has observed this object for two nights
and detected superhumps with a period of 2.512(7) hours.
The amplitudes of superhumps were large (~0.3 mag).
Continued observations are encouraged!
