Hi All,

After finding the alert, I made yesterday evening an observation of this star with a 25cm newton f4.7 and QHY 268M camera with a photometric V filter. 
At the end of the observation run the altitude neared 30degrees, so I stopped. 

This is the curve of it, no outliers were removed. Used the sequence that can be found at the AAVSO. 
Observations are reported there too :

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.

Best regards,
Yusuke
