We present a catalogue of positions and photographic R magnitudes at observed maximum and minimum brightness for 1061 variable stars newly detected in the direction of the Bright Cloud B in Sagittarius. The limiting R magnitude of the survey is about 18. Most of these stars are long period variables. Taking into account the previously published lists (Terzan et al. 1982, 1988, 1991), the total number of new variable objects discovered in the surveyed 100 square degree field amounts to 4430.
Key words: the Galaxy: structure; center / stars: variables; AGN, post-AGN
Plate scanning done with MAMA. MAMA is developed and operated by INSU (Institut National des Sciences de l'Univers).
