  We present the first results from the MultiSite Spectroscopic Telescope
(MSST) observations of the sdBV star PG1605+072. Pulsating sdB stars (also
known as EC14026 stars) offer the chance to gain new insights into the
formation and evolution of extreme Horizontal Branch stars using the tools of
asteroseismology. PG1605+072 is an outstanding object in its class, with the
richest frequency spectrum, the longest periods, and the largest variations.
The MSST campaign took place in May/June 2002 immediately following the Whole
Earth Telescope Xcov22 run, which observed PG1605+072 as an alternate target.
We will first give an overview of the project and its feasibility, after which
we will present the massive data set, made up of 399 hours of photometry and
151 hours of spectroscopy. The overall aims of the project are to examine
light/velocity amplitude ratios and phase differences, changes in equivalent
width/line index, and wavelength-dependence of photometric amplitudes, and to
use these properties for mode identification.
