Abstract

We present ¹²CO(1-0) molecular line and BV CCD observations towards 0311-7651, a region in the Magellanic Bridge where cold atomic Hydrogen has previously been detected by Kobulnicky & Dickey. Additionally, BV images of a comparison field 1^o to the South were taken. No CO was detected to a limit of 0.06 Kelvin, and the colour-magnitude diagrams show no evidence for a stellar association in either field.

Key words: galaxies: ISM galaxies: Magellanic Clouds galaxies: photometry radio lines: galaxies radio lines: ISM

* Based on observations made with the Danish 1.54-m and SEST telescopes at the European Southern Observatory, La Silla, Chile.
