General Description

This is a simple spectroscopic observation of a relatively bright (V=15.26)
 sdB star. To minimise slit losses for this very blue target it would help if the
 rotator could be (re-)set to the parallactic angle at the beginning of each of the
 three exposures specified in the OB. In order to achieve our science objective,
 we require a high (minimum ~160, ideally 200-250 at the central wavelength) S/N
 ratio. This should be achievable within the time allocated if the constraints on
 the observing conditions are met; the observing constraints may be violated slightly
 if this is compensated for by a longer exposure time and the minimum S/N specified
 is nevertheless reached.
