A photometric study of the Bright Cloud B in Sagittarius. VIII. 1061 new variable stars
Abstract
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 (\cite[Terzan et al. 1982, 1988, 1991]{ref12}), the total number of new variable objects discovered in the surveyed 100 square degree field amounts to 4430. Plate scanning done with MAMA. MAMA is developed and operated by INSU (Institut National des Sciences de l'Univers). Based on observations made at the Palomar and European Southern Observatories. The whole of Table 3, as well as the full catalogue of 4430 variables are only available in electronic form at CDS via anonymous ftp cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/Abstract.html
