TCP J18513997+3522412: confirmation as a WZ Sge-type dwarf nova
Sano-san and Sjoerd Dufoer reported further time-resolved observations of TCP J18513997+3522412. These show double-peaked modulations with a period of 0.0563(1) d and an amplitude of ~0.15 mag, likely large-amplitude early superhumps. Thus, I confirm that TCP J18513997+3522412 is a new WZ Sge-type dwarf nova.
This object is currently ~15.0 mag, and further time-resolved observations are encouraged. Best regards, Yusuke
