Abstract:	Photometric observations of some dwarf novae have shown periodic variation, which has been attributed to non-radial pulsations of the white dwarf. Our high time-resolution observations of two of these objects (GW Librae and SDSS J161033.64−010223.3) in quiescence show the strong pulsations modes reported by previous authors, as well as some additional periodicities with much smaller amplitudes. We also observed GW Lib some months after outburst, and find the heating of the white dwarf has suppressed the pulsations.
