OT_J102146.4+234926: orbital modulations confirmed

    Using our data on 18, 19, and 22 Dec., we performed a period 
analysis and obtained a period of 0.05590(3) d, significantly 
shorter than the superhump period (0.05628d).  
The period is 0.6% shorter than the superhump period.  
These periods are reminiscent of the orbital and superhump period in 
WZ Sge-type dwarf novae.  We put an average profile of orbital 
modulations in:

    The object again started a gradual fading on 21 Dec.
