In August and September 2003, the Whole Earth Telescope (WET) collaboration observed the pulsating subdwarf B (EC~14026 class) star KPD~1930+2752. This global, multisite campaign obtained time-series data to examine the pulsation structure of the sdB star. The system is a close binary (orbital period of 2.4 hours) with an sdB primary and an unseen (probably white dwarf) companion. The combined binary mass exceeds 1.5 solar masses and will likely merge within 200 million years. We present a first-look analysis of the WET data.
