High-resolution H2O maser observations toward IRAS sources in Bright-Rimmed Clouds

Bright-Rimmed Clouds (BRCs) are clouds that have been compressed by an external ionization-shock front. We present the rst high resolution VLA observa-tions of 20 of these BRCs in the northern hemisphere. We detected water maser emission from three objects: IRAS 21346+5714 (BRC 36), IRAS 21388+5622 (BRC 37) and IRAS 21445+5712 (BRC 39). The low detection rate supports the evidence that BRCs produce mostly low-luminosity objects, for which maser emission is weak and episodic, and suggests that the embedded sources are in
