Abstract (from CDS):

The Metsaehovi 13.7-m radio telescope was used to search for emission in the 95 GHz 8₀-7₁ A⁺ transition of methanol towards a number of star-forming regions. Eleven known 44GHz (7₀-6₁A⁺ transition) methanol masers were observed; 95GHz emission was found towards nine sources, five of which are new detections. For two sources, S 140 and R 146, only upper limits were obtained. Most likely the 95GHz line is masing in all cases with detected emission, except for W51 e1/e2 toward which a broad thermal emission line is observed. The integrated flux density is higher at 95GHz than at 44GHz. It is suggested that the 95GHz methanol masers are as widespread as the 44GHz masers.
