New flare stars and variable stars in the Sco-Oph region found in 1977

Abstract

In 1977, we continued our cooperative observations in the Sco-Oph region with the Schmidt telescope of the Beijing Observatory and the twin-tube refractors of the Purple Mountain Observatory and the Beijing Observatory. After blinking and measuring, two flare stars and 15 variable stars were found. The results are given in TABLE 1. The identification charts and photographic reproduction of the two flare stars during their outbursts are presented in Fig. 1. The identification charts of the variable stars, with the exception of two variable stars in M4, are shown in Fig. 2. The light curves of most of the variable stars are presented in Fig. 3
