[vsnet-alert 26371] ASASSN-21tq: likely superhumps
by Taichi Kato 01 Nov '21

01 Nov '21

ASASSN-21tq: likely superhumps Itoh-san, Kiyota-san, Berto Monard and Josch Hambsch have reported observations. The most recent data (since Oct. 28) seem to show superhumps with a period of 0.0588(1) d and an amplitude of 0.10 mag. The data were not in very good quality (weather condition) and further data are needed for confirmation.
