Most stars end up as white dwarfs on their evolutionary track. A knowledge of the structure of white dwarfs puts constraints on their prior evolutionary stages. By conducting co-ordinated continuous long term observations of these pulsating objects, high precision light curves can be generated to study their environments. We report preliminary photometric observations of WD J1524 from Mt Abu Infrared Observatory (MIRO). The photometric data collected for this source during 27-28 May 2007, though not of sufficient duration, indicate a periodicity of 210 s. These observations provide us confidence to join the future observing programs of Whole Earth Telescope (WET) for such studies.
