[vsnet-campaign-dn 17394] FL Psc: rapid fading on June 26
by Taichi Kato 01 Jul '23

FL Psc: rapid fading on June 26 Josch Hambsch reported further observations. The object started fading on June 25 and now at mag 15.0. We probably observed the growth of stage C superhumps and the behavior is not particularly different from the 2004 superoutburst. A rebrightening is expected.

[vsnet-campaign-dn 17393] ASASSN-23es: SU UMa-type dwarf nova
by Taichi Kato 26 Jun '23

26 Jun '23

ASASSN-23es: SU UMa-type dwarf nova Josch Hambsch has reported observations. Due to the relatively large scatter (probably due to unfavorable weather) and sparse sampling, it was difficult to detect superhumps. An analysis using the entire data yielded a period of 0.07211(3) d (amplitude 0.11 mag).

Re: FL Psc started showing superhumps > According to observations by Josch Hambsch, this object > started to show ordinary superhumps on June 21 at 12.0 mag, > later than in 2004. This may be the start of stage C superhumps rather than appearance of superhumps. The current outburst had a peak magnitude of 9.7 on June 1.
