UY Pup is a little studied, frequently out bursting dwarf nova whose brightness varies from V ~ 13.5 mag in outburst to V ~ 15.8 mag in quiescence, which typically lasts ~15…25 d. We observed it spectroscopically at the INT in La Palma on 1989 Febuary 15 and 16 during outburst maximum. In this outburst, the rise lasted at least 3 d and there was a long decline of about 6…9 d. The whole outburst lasted about 18 d (Mattei, private communication).
