| Abstract: | A spectroscopic study of the frequently outbursting dwarf nova UY Pup has been undertaken whilst the system was in outburst.
The Hα andHβ line profiles in UY Pup are typical of low inclination dwarf novae after outburst maximum. No evidence for two
components is seen in the emission lines. Using radial velocity measurements of Hα, we find the best fit orbital period for
the system to be 10.22 ± 0.19 h(although we cannot with certainty rule out a period of 7.13 ± 0.14 h).We place limits on the
system parameters. We also present multicolour photometry of UY Pup in quiescence.
