  We present the aim and first results of the RApid Temporal Survey (RATS) made
using the Wide Field Camera on the Isaac Newton Telescope. Our initial survey
covers 3 square degrees, reaches a depth of V~22.5 and is sensitive to
variations on timescales as short as 2 minutes: this is a new parameter space.
Each field was observed for over 2 hours in white light, with 12 fields being
observed in total. Our initial analysis finds 46 targets which show significant
variations. Around half of these systems show quasi-sinusoidal variations: we
believe they are contact or short period binaries. We find 4 systems which show
variations on a timescale less than 1 hour. The shortest period system has a
period of 374 sec. We find two systems which show a total eclipse. Further
photometric and spectroscopic observations are required to fully identify the
nature of these systems. We outline our future plans and objectives.
