CSS J174033.5+414756: very unusual object early superhumps with 67m period?

   Colin Littlefield has reported observations.  The data
seem to show double-wave modulations similar to early superhumps
(full amplitude 0.04 mag).  The period is astonishingly short:
0.0466(1) d.  Further continued observations are very strongly
needed.  The object may be WZ Sge-type analog of ultrashort
period CVs with evolved secondaries (or halo CV?).
Spectroscopic observations are also highly wanted.
An analysis of CRTS data yielded possible weak periodicity
at 0.04702 d, but this needs confirmation.
