Abstract :
[en] A field in the Sagittarian bright cloud in the direction of the Galactic center is investigated by means of the B, V, and R Schmidt plates at the ESO, and 1165 variable stars are reported. The position, R magnitudes, epochs, and amplitudes of variation are given for each star, and the surface density per square degree of variable stars increases from 1.7 to 65. The number of variables in the present field is similar to that for field A, and variables of type L and/or M are more densely numerous toward the center of the Galaxy than at other locations. Of the objects listed, 65 are given with potential classifications based on morphological data from the B and R Schmidt plates. The preliminary observations suggest a success rate of 42 percent on the precise prediction of the object types.
