Dear Yusuke,

 

Note that I already reported the detection of superhumps with a period of 0.056 +/- 0.001d, and classification of MASTER OT J213908.79+161240.2 as a WZ Sge-type object, in my report of Sep 27 at 2:20 UT.


Best regards

Tonny Vanmunster

MASTER OT J213908.79+161240.2: likely showing (early) superhumps

 

Kyoto Univ. Obs. have reported observations of MASTER OT J213908.79+161240.2 for two nights. 

I see a sign of superhumps with a period of  0.0577(3) d, although I cannot judge whether this is double-peak or not due to the quality of data.

Since it's only 2 days from the discovery, this modulation could be an early superhump. It's short period also suggests that this system is a good candidate for WZ Sge-type dwarf nova.

 

More observation will clarify the existence of early superhumps and the period of observation.
