E. Green, in collaboration with Gilles Fontaine (Univ. de Montreal), Stephane Charpinet (Univ. de Toulouse), Suzanna Randall (ESO), and for two of the campaigns Roy Ostensen (Univ. Kuleuven), conducted the first four major asteroseismological campaigns on pulsating subdwarf B star using the Mont4k CCD camera on the Mt. Bigelow 1.55 m telescope. The first campaign was a test, during which we acquired 8 nights of data over a time baseline of 2 months for the p-mode pulsator, PG0911+456, to see how well the Mont4K camera could do with pulsational modes as short as 150 s in a star as faint 14.6 magnitude. The results (Randall et al, 2007) were spectacular, as we detected 7 pulsational modes, sufficient to determine a unique seismic model. The second campaign, on one of the brighter known sdB p-mode pulsators, the 12.9 magnitude star PG1219+534, resulted in 198 hrs of observation over a time baseline of 2.5 months, giving the lowest noise FT and highest time resolution obtained at that time for one of these pulators. A third campaign was conducted for the composite spectrum sdB, PB8783, 170 hours over a 2 month time baseline. The fourth campaign, on one of the rare hybrid p-mode+ g-mode sdB pulsators, HS0702+6043, was begun in November 2007, with the expectation of acquiring close to 400 hrs of observations over 4.5 months. In sum, these campaigns have now proven that the Mont4k CCD camera on the Mt. Bigelow telescope is a uniquely powerful combination, capable of obtaining pulsational data for evolved stars with a combination of sensitivity plus time resolution that has not been matched with any other telescope/instrument combination.
