Abstract
Low-dispersion spectra showing bright lines of Proxima Centauri, RR Telescopii and of three long-period variables in 47 Tucanae are described. Proxima Centauri is of dMe type, the emission lines apparently varying in intensity. RR Telescopii underwent a rather abrupt transition from F-type absorption to emission plus continuous during the period 1949. August to September.Keywords
