Re: [vsnet-chat 1990] Re: NY Ser Congratulations, Lew! The obtained period of 0.10-0.11 day quite well agrees with the previous study (Nogami et al.), which gave the best estimate of the superhump period of 0.106 +/- 0.001 day. Wishing for your further successful photometry, and please keep us informed! The superhump amplitude obtained by Nogami et al. reached 0.3 mag, which is also in good agreement. Any comments, Nogami-san? Regards, Taichi Kato
