[vsnet-campaign-dn 17419] V2276 Sgr: entered plateau
by Taichi Kato 19 Jul '23

19 Jul '23

V2276 Sgr: entered plateau According to Josch Hambsch's observations. Entered a plateau (or standstill) on July 16 before the ending of the superoutburst. The favored period is 0.01963 d (amplitude 0.05 mag). All the behavior strengthens the AM CVn-type classification. The next superoutburst is expected in October and high-cadence time-resolved photometry during the earliest part of the superoutburst will detect superhumps with larger amplitudes.
