Abstract

We have detected OH maser emission from four stars classified at optical wavelengths as F- or G-type supergiants. The spectral characteristics of the OH masers are described. For the source HD 101584, images of the OH 1667 MHz maser emission obtained with the Australia Telescope show that the masers are located in a bipolar outflow. The stars are likely to be proto-planetary nebulae.
