  We use ultraviolet imaging taken with the XMM-Newton Optical Monitor
telescope (XMM-OM), covering 280 square arcminutes in the UVW1 band (effective
wavelength 2910 Angstroms) to measure rest-frame ultraviolet (1500 Angstrom)
luminosity functions of galaxies with redshifts z between 0.6 and 1.2. The
XMM-OM data are supplemented by a large body of optical and infrared imaging to
provide photometric redshifts. The XMM-OM data have a significantly narrower
point-spread-function (resulting in less source confusion) and simpler
K-correction than the GALEX data previously employed in this redshift range.
Ultraviolet-bright active galactic nuclei are excluded to ensure that the
luminosity functions relate directly to the star-forming galaxy population.
Binned luminosity functions and parametric Schechter-function fits are derived
in two redshift intervals: 0.6<z<0.8 and 0.8<z<1.2. We find that the luminosity
function evolves such that the characteristic absolute magnitude M* is brighter
for 0.8<z<1.2 than for 0.6<z<0.8.
