TCP J08374922+0134065: new WZ Sge-type dwarf nova with large early superhump amplitude

TCP J08374922+0134065 was discovered by Y. Nakamura on 3rd April at 14.7 mag. Based on the suggested counterpart (GALEX J083749.2+013407) with g=20.22(2) and the brightest ASAS-SN measurement with g~13.4 mag, the outburst amplitude is 6.8mag.

Itoh-san has reported the time-resolved observations on 6th April and the light curve shows a double-peaked modulation with a period of ~0.059 d and an amplitude of 0.2 mag with possible eclipses.

Thus TCP J08374922+0134065 is a new WZ Sge-type dwarf nova with high inclination. 

Time-resolved observations are strongly encouraged.
