A large-format infrared camera has been used for repeated observations of a 24 * 24 arcmin^2 region around the Galactic Centre. The survey is carried out at \it K (2.2\mum), with single-epoch coverage at \it H (1.65\mum) and \it J (1.25\mum). So far, the observations have extended over two seasons and it is intended that they will continue for one more. The brightest ~200 objects within each 5 * 5 arcmin^2 sub-field have been examined for variability. Preliminary processing of the data has revealed about 280 likely variables in the overall field. Their positions have been determined relative to stars in the STScI Guide Star Catalog. They include several previously known OH/IR stars.
