HS0702+6043 (DW Lyn) is one of the very few known sdB pulsators which exhibit both pressure- and gravity-mode oscillations. Given its high potential for asteroseismology, we carried out an extensive campaign in integrated light photometry at the Steward Observatory 1. 6 m Kuiper Telescope using the new CCD camera Mont4K, a joint venture between the Université de Montréal and the University of Arizona. Over a period starting November 1st 2007 up to March 14th 2008, we were able to gather some 424. 5 hours of useful data. To our knowledge, never before a pulsating sdB star has been observed at such high frequency resolution and sensitivity. We present the results of a preliminary analysis of this unique data set.
