The position of Sagittarius A* at the Galactic center

The absolute position of the compact radio source at the dynamical center o f the Galaxy, Sagittarius A*, was known only to an accuracy of 0".2 in spit e of its accurate location with respect to near-IR stellar sources to withi n 30 mas. To remedy this poor positional accuracy, we have selected 15 high -resolution, high-frequency VLA observations of Sgr A* carried out in the l ast 13 years and determined the weighted average position with the average epoch 1992.4 to be at alpha, delta (1950) = 17(h)42(m)29.(s)3076 +/- 0.(s)0 007, -28 degrees 59'18".484 +/- 0."014 or alpha, delta (2000) = 17(h)45(m)4 0.(s)0383 +/- 0.(s)0007, -29 degrees 00'28"069 +/- 0".014, which agrees wit h earlier published values to within the 0".2 error bars of the earlier mea surements. An accurate absolute position of Sgr A* can be useful for its id entification with sources at other wavelengths, particularly in soft and ha rd X-rays, with implications for the models of a massive black hole at the Galactic center.
