 TCP J07463511-0746335: new likely SU UMa-type dwarf nova

  Maehara-san and Kiyota-san have reported observations.  Although
there were no prominent variations in Maehara-san's Feb. 22 observations,
possible superhumps (amplitudes 0.25 mag) were present in Kiyota-san's
Feb. 26 observations.  An analysis favors a period of 0.068(1) d.
The object faded by 0.08 mag/d between these observations.
Confirmatory observations of superhumps are encouraged.
