[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.

Berto Monard
