Date: Wed, 02 Apr 2003 15:02:22 +0200 From: "Berto Monard" <LAGMonar@csir.co.za> Subject: [vsnet-alert 7679] IGR J17464-3213 / update No optical counterpart was detected on the image of IGR J17464-3213 taken on 31/3/03 at the Bronberg Observatory. Assuming a 1" accuracy (0.1" in RA) for the radio location of the transient, there is nothing visible on the image that comes within 10". There seems to be a 'weak' indication of an extended source some 15" South of the radio position. It's most probably unrelated. There are some bright radio sources also detected nearby, though not close enough (>20") to the reported radio detection. It is certainly not impossible that the XT hides within one of those lesser bright IR that were not on the image. Again, as in the case of previous sources, all of the most prominent candidates within the error radius (in this case 2') around the original position, turned out to be bright 2Mass sources. I might try another image, but like other such transients it will probably hide forever from small telescopes. Regards, Berto Monard Bronberg Observatory / CBA Pretoria
