[vsnet-newvar 10177] ASASSN-23es: SU UMa-type dwarf nova
by Taichi Kato 26 Jun '23

26 Jun '23

ASASSN-23es: SU UMa-type dwarf nova Josch Hambsch has reported observations. Due to the relatively large scatter (probably due to unfavorable weather) and sparse sampling, it was difficult to detect superhumps. An analysis using the entire data yielded a period of 0.07211(3) d (amplitude 0.11 mag).
