[vsnet-outburst 29549] TCP J06442271+1549388: new WZ Sge-type dwarf nova
by Taichi Kato 18 Jan '23

18 Jan '23

TCP J06442271+1549388: new WZ Sge-type dwarf nova Itoh-san and Kiyota-san have reported observations. The data show clear double-wave humps (amplitude 0.05 mag). The period was 0.0529(5) d (single-night baseline). Although The profile was somewhat different from those of typical WZ Sge-type early superhumps, the large outburst amplitude supports this classification.
