A photometric study of the bright cloud B Sagittarius: first results.
Abstract
During the past years, Ors. Agop Terzan and Alain Bernard of the Lyon Observatory, France, have been studying Schmidt plates of fields in the direction of the galactic centre. Most of the plates come from the ESO Schmidt telescope and a thorough intercomparison of plates in different colours and from different epochs have revealed a large number of new variable stars. Some stars have been found to possess large proper motions and some diffuse objects (galaxies, planetaries, nebulae?) were also discovered.
