Swift XRT Position for IGR J18490-0000
J. P. Halpern
On 2006 March 5-6, and again on March 9 the Swift XRT observed a source at quicklook position R.A. = 18h49m01.4s(01.5s), Decl. = -00°01′19.5″(18.4″) (J2000) that is the probable counterpart of IGR J18490-0000 (Bird et al. 2006). There is possibly one faint counterpart in the 2MASS at R.A. = 18h49m01.82s, Decl. = -00°01′19.0″ (J2000) that is not visible on the DSS.
It is very convenient that a bright star, HD 174181 (K5) at
R.A. = 18h49m21.282s, Decl. = -00°00′13.00″(J2000)
is also detected by Swift, at position
R.A. = 18h49m21.1s(21.1s), Decl. = -00°00′14.3″(14.9″) (J2000),
which should allow an improvement of the astrometry.
