BHR160 is a virtually unstudied cometary globule within the Sco OB4 association in Scorpius at a distance of 1600pc. It is part of a system of cometary clouds which face the luminous O star HD155806. BHR160 is special because it has an intense bright rim. We attempt to derive physical parameters for BHR160 and to understand its structure and the origin of its peculiar bright rim. BHR160 was mapped in the ^12^CO, ^13^CO and C^18^O (2-1) and (1-0) and CS (3-2) and (2-1) lines. These data, augmented with stellar photometry derived from the ESO VVV survey, were used to derive the mass and distribution of molecular material in BHR160 and its surroundings. Archival mid-infrared data from the WISE satellite was used to find IR excess stars in the globule and its neighbourhood.
