dc.descriptionWe present a preliminary analysis of time series photometry on the pulsating subdwarf B star PG1336-018 acquired as part of two Whole Earth Telescope runs. PG1336-018 is a multi-mode pulsator with at least 15 periods centered around 175 seconds. It is also an HW~Vir-type eclipsing binary with a period of 2.4 hours. Though over 20 pulsating subdwarf B stars have been discovered, only a few have resolved temporal spectra and still fewer have identified pulsation modes. We analyze features unique to the eclipsing binary system of PG1336-018 as a means of identifying pulsation modes.
