The distance to an outer Galaxy star forming region
Published online by Cambridge University Press: 01 October 2007
Abstract
We performed phase-referencing VLBI astrometric observations of the H2O maser source IRAS 02395+6244, located well beyond the solar circle. We measured its heliocentric distance to be 5.49 ± 0.80 kpc, implying a Galactocentric distance of 12.5 ± 0.5 kpc and a distance of 270 ± 40 pc above the Galactic plane.
