[vsnet-campaign-dn 16940] ASASSN-18jh: deeply eclipsing SU UMa star currently in superoutburst, but almost ending
by Taichi Kato 13 Feb '23

13 Feb '23

ASASSN-18jh: deeply eclipsing SU UMa star currently in superoutburst, but almost ending Using ATLAS forced photometry (Tonry et al. 2018; Shingles et al. 2021) I obtained a period of 0.0783463(1) d. Eclipses were 1.3 mag deep in quiescence + orbital hump. ATLAS Intranight variations during the current long outburst suggest superhumps. A high inclination is suspected.
