  Recent results of microlensing surveys, show that 10-20% of the dark halo
mass of the Milky Way consists of compact objects. The masses of these compact
objects range from 0.1 to 1 solar mass. New theoretical cooling models for
white dwarfs, and the detection of faint blue high proper motion objects, imply
that ancient white dwarfs might make up part of this population. In this pilot
project, using data from the C and D patches of the ESO Imaging Survey and data
obtained at CTIO, we attempted to find such halo white dwarfs in the solar
neighbourhood. With a time baseline of approximately one year between data sets
and a limiting I-band magnitude of 23, we can find these high proper motion
objects up to distances of 85 parsecs. In the 2.5 square degrees studied so far
we have found three high proper motion candidates.
