[vsnet-chat 9407] ELAISN1MOS15-02 classification and period

ELAISN1MOS15-02 classification and period https://arxiv.org/abs/2305.13371 "Cataclysmic Variables from Sloan Digital Sky Survey V -- the search for period bouncers continues" I could not confirm the claimed period for ELAISN1 MOS15-02 = SDSS J160809.54+542131.4. The fading rates of outbursts appear to me to small for the claimed period. This object is still a mystery one to me. SDSS J182643.55+613816.5 is the already known object MASTER OT J182643.42+613816 (SU UMa).

[vsnet-chat 9397] MASTER OT J081110.46+660008.5: multiple rebrightening, short superoutburst interval
by Taichi Kato 15 May '23

15 May '23

MASTER OT J081110.46+660008.5: multiple rebrightening, short superoutburst interval Based on ATLAS, ZTF and ASAS-SN. The 2021 superoutburst was followed by multiple rebrightenings. A new superoutburst was found in 2017 in ATLAS and ASAS-SN. This interval was short for a WZ Sge star with multiple rebrightenings.
