Scientific paper

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.
