Abstract:
    The Cambridge Low Frequency Synthesis Telescope has been used at 151
    MHz to survey a region of 1393 square degrees, in the range RA 9h to
    16h, Dec 20deg to 35deg, with an angular resolution of
    108x108cosec(dec) arcsec^2^. The rms noise on the maps is in general
    ~35-55 mJy/beam but varies considerably and exceeds this in some
    areas. We have extracted sources with signal-to-noise ratio > 5.5, a
    total of 5526, and present a catalogue of their positions and flux
    densities.
