[vsnet-newvar 9531] ASASSN-22ng: most likely SU UMa star fading from superoutburst
by Taichi Kato 17 Nov '22

17 Nov '22

ASASSN-22ng: most likely SU UMa star fading from superoutburst Josch Hambsch and Itoh-san have reported observations. The object showed a typical SU UMa-type superoutburst followed by rapid fading on Nov. 15. Although some observations showed likely superhumps, the period has not been reliably determined due to short observations or poor S/N. Likely around 0.07 d from observations on Nov. 4. The object is almost certainly an SU UMa star and observations in better condition during a future superoutburst are very much desirable.
