SBS1108+574: ultrashort-period CV?

   Colin Littlefield has reported observations.  There were 
large-amplitude (0.2-0.3 mag) modulations with an apparent
period of 0.93 hours or 1.86 hours if it was double-wave
modulations (Littlefield's estimates).  I am not confident
which is the case, but given the very blue SDSS color, I'm
tempted to suspect that the object might even be a very unusual 
object with a period less than one hour.  Further observations are 
very strongly desired.
Spectroscopic observation will also be interesting.
