   Observing_Description:

         Two exposures with the G140L grating will be required to
         cover the spectral region from 1300Angstrom\ to 1700Angstrom.
         We estimate the exposure time for a S/N=25 at 55 minutes for
         1415Angstrom\ to 1700Angstrom, and 55 minutes from
         1300Angstrom\ to 1585Angstrom. Thus, three full orbits will
         be required.

Abstract:                

    We propose to obtain a 1300Angstrom\ to 1700Angstrom\ spectrum
    of HD44179, the central star of the Red Rectangle Nebula, with
    GHRS using the G140L grating. With this spectrum, it will be
    possible to resolve and derive accurate wavelengths and
    strengths of the various unidentified absorption and emission
    features, and should enable us to identify the molecules
    responsible for them.
