The element of GCVS is min = 2427333.500 + 1.117455 x Cycle.
The following light curves.

I think that I differ the period.
Strohmeier et. al. found YY Cet in 1966. ( IBVS 140 )
The name is BV795.
YY Cet was registered in GCVS by the 57th name list in 1970.
The name was changed. ( BV795 ---> YY Cet )
The element of GCVS is min = 2427333.500 + 1.117455 x Cycle.
I read the paper of this star.

The element of this paper is min = 2445259.0560 + 0.7904596 x Cycle.
I rewrote the light curve.
