  We present results of phase-referencing VLBI observations of water maser
sources in Orion-Monoceros Molecular Clouds with VERA (VLBI Exploration of
Radio Astrometry), which is newly constructed Japanese VLBI network. Main
topics of this poster are (1) the aim of one of the first scientific projects
for VERA "3-Dimensional Structure and Kinematics of Orion-Monoceros Molecular
Cloud Complex"; (2) current status (sensitivity and astrometric accuracy) of
phase-referencing VLBI observations with VERA; and (3) results of VLBI
observations of water sources in Orion-Monoceros Molecular Clouds with VERA.
