Discovery of a Large-Amplitude SU UMa-Type Dwarf Nova, KV Andromedae
Abstract
A faint dwarf nova, KV And, was observed for two nights during its long outburst in 1993 November. V-band CCD photometry revealed superhumps with a period of 0.07520 (+/- 0.00003) d or its alias 0.07427 (+/- 0.00003) d, and an amplitude of 0.28 mag. This discovery confirms KV And as being a new member of SU UMa-type dwarf novae, and makes it as a good candidate for being a TOAD (Tremendous Amplitude Dwarf Nova).
