VV Puppis, a dwarf-nova binary with a 100 min period (Herbig 1960) was observed on two occasions. On 2nd February 1979, VV Puppis was in a faint inactive state. On the other hand it was bright and active on 14th June 1979. Spectral and polarimetry observations were made on both these occasions using IDS (modified as polarimeter) at the f/15 Cassegrain focus of the 4 meter Anglo-Australian Telescope. Spectral range covered was from 3600 Å to 7000 Å with a resolution of 10 Å. The star and sky apertures both were of size 3 × 4 sec of arc and 40 sec apart.
