D. ; Le Squeren, A. M. ; Scalise, E., Jr. Abstract Eight new SiO maser sources were detected at 43.122 GHz in a search made in 1977 August with the Itapetinga radio telescope, from a search list of about 80 objects which included Mira variables, M supergiants, carbon stars, and S stars. One of the new sources is a symbiotic star, the first star of this type to present maser emission. Eighteen previously known SiO sources were reobserved, and the H2O emission at 22.235 GHz of the SiO sources was observed at the same epoch, to provide a measurement of ratios of SiO to H2O maser fluxes. The interesting implications of our results are discussed.
