                                   ABSTRACT

      Far-ultraviolet photometry of stars in a field in Monoceros in the
    wavelength range from 1230 A to 1600 A has been carried out using data
    from an electrographic Schmidt camera carried on a sounding rocket.
    Ultraviolet magnitudes were extracted for 602 objects in the field.
    Fifty-eight percent were tentatively identified with visible stars
    using the SIMBAD data base while another 25% are blends of objects too
    close together to separate with our resolution.  Eleven of the UV
    objects coincide with parts of the star clusters NGC 2169, NGC 2244,
    and NGC 2264 in which individual stars cannot be resolved. As in
    previous studies, the majority of the identified ultraviolet sources
    are identified with early-stars.  However, there are a significant
    number for which no such identification was possible, and we suggest
    that many of these are nearby white dwarfs.
