摘要

We measured the trigonometric annual parallax of an H$_2$O maser source associated with the massive star-forming region IRAS 06061$+$2151 with VERA. The annual parallax of 0.496$\ \pm\ $0.031 mas, corresponding to a distance of 2.02$^{+0.13}_{\-0.12}\ $kpc, was obtained by 10 epochs of observations during the period from 2007 October to 2009 September. This distance was obtained more accurately th...
