[vsnet-campaign-dn 16128] ASASSN-17ag superhumps
by Taichi Kato 15 Nov '21

15 Nov '21

ASASSN-17ag superhumps Observations by Itoh-san clearly detected superhumps. Since the 2019 observation covered only a single night, subsequent observations during the current superoutburst provides an opportunity to obtain an accurate superhump period.
