Abstract: We present new CCD time-series photometry of GW Librae obtained in 2012 using the one metre telescope at Mt John University Observatory in New Zealand with the Puoko-nui CCD photometer. Observations in May 2012 show the presence of a strong non-sinusoidal pulsation with a 19 minute period that varies slightly in frequency over the 6 nights of observations.
