KV ANDROMEDAE
Taichi Kato, Kyoto University Japan e-mails details of the outburst
of KV And:
"A faint dwarf nova KV And was detected in outburst by M. Iida
(Nagano, Japan, a member of VSOLJ) using 16-cm reflector and ST-6
CCD.
Observations follow:
0502 MM DD.DDD MAGN MS SEQ OBSERVER NOTES SOURCE
1993 11 03.476 [16.6 C GS *Iida, M. 16-cm refl. + ST-6 VSOLJ

1993 11 16.461 14.3 V GS *Kato, T. 60-cm refl Mail(kat)
The outburst was subsequently confirmed by T. Kato and C. Kunjaya
(Ouda Station of Kyoto University, Nara, Japan) using a 60-cm
reflector + CCD.
Time-resolved CCD photometry on Nov. 16, 1993 revealed distinct
superhumps with an amplitude of 0.27 mag in V and a period of
1 hr 44 min.
Another superhump maximum was independetly detected by M. Okyudo
(Nishi-Harima Astronomical Observatory, Hyogo, Japan) by a 60-cm
refrector and a CCD. The superhumps showed a peaky maximum and a
gradual decline, quite typical for superhumps early in their
development.
Because this dwarf nova is one of the most distant (halo) dwarf
nova with determined physical parameters, further observations are
strongly encouraged to determine the accurate superhump period,
orbital period and so on.
The object is located at:
02h 14m 08s.35 +40 27' 34".6 (1950)
14.6-22.5:p (GCVS4)
