Abstract
We have observed 11 dwarf novae during their outbursts, and analysed their light curves for the presence of oscillations. We have found oscillations in four objects: KT Per (22.5–29.5 s), SY Cnc (33.5–20.3 s), AH Her (24.1–25.0 s) and EM Cyg (16.6 s). Oscillations were found to occur during both the ascending and descending parts of the outbursts. For three objects (KT Per, SY Cnc and AH Her) relationships were found between the period of oscillation and the brightness of the star relative to its minimum brightness.Keywords
