Abstract : The detection of H2O maser emission is reported from three new galactic regions: a point 0.9 min NE of T Tauri, and towards the HII regions G29.9-0.0 and G0.55-0.85. The T Tauri water source is not coincident with any known optical object; comparison of the H2O and CO observations of this region suggests the presence of an embedded protostellar region in the molecular cloud. These sources and those in S140-IR and Mon R2 were monitored for time variations and found that all sources except T Tauri are time-variable on the scale of a month. A model for the varying component of Mon R2 is proposed.
