updated period of TCPJ21040470+4631129

Tonny Vanmunster, Geoff Stone, Tamás Tordai and Hiroshi Itoh have
reported recent observations of this object.
After its 5th rebrightening, TCPJ21040470+4631129 is now around 15 mag
which is as faint as it before the 5th rebrightening.
But the PDM analysis suggests the period of  0.0542(1) day. This
period is much closer to its superhump period (~0.0542 day; stage B
superhump period) than the orbital period (~0.0535 day; early
superhump period). This might mean that the accretion disk keeps its
non-axisymmetric structure.

More consecutive observations are encouraged and another rebrightening
could be expecterd.
