Description
We present a photometric survey aimed at the identification of variable
stars in the galactic globular cluster ω Cen. Our photometric
catalogue is based on ~ 400 exposures of the central region of the
cluster(Fov ~ 15' × 15') collected with the Danish Telescope. The
catalogue has an accuracy of about ~ 0.02 mag at B ~ 18 mag. We present
here preliminary results concerning the possible identification of two
variable stars and an eclipsing binary candidate in ω Cen.
