We aim to survey a large area of sky (4000 sq. degs) in the near-IR to a depth which will match the Sloan Digital Sky Survey (SDSS), making a combined dataset covering a factor of 6 in wavelength. Its combination of area, depth and multi-filter coverage make it a powerful tool for determining statistics on common objects (stars, galaxies, clusters of galaxies) and isolating extreme objects (low mass dwarfs and high redshift quasars). At our standard shallow survey depth, the magnitude limits of the survey are J=20.0, H=18.8, K=18.4 over a total area of 4000 sq. degs. Observations are also desired in a proposed new filter Y covering 0.97 - 1.07 micron that would reach a depth of Y=20.5.
