On October 1st, 17:42 UT, Chandra has performed a 20ksec HETGS observation of the source IGR J17497-2821 recently discovered by INTEGRAL (Soldi et al., ATEL #885). Our preliminary position estimate is (J2000) RA: 17 49 38.04, Dec: -28 21 17.4. As the source is quite bright, the positioning reaches the Chandra absolute astrometric accuracy that is usually better than 1". Thus our reported position is expected to be accurate to within this value, dominated by current systematic uncertainties which are likely to improve with further analysis.
