Hi,
unfiltered CCD observations were done at the Bronberg Observatory
on 03 May 2003; 00.00 UT in search of an optical counterpart for IGR
J17597-2201 around the position published in ATEL #155.
A deep field (DF) image with limiting magnitude exceeding 20.0CR was
obtained by co-adding 10 images.
All new and some strongly brightened objects visible on the DF image in
comparison to DSS2-red were checked against 2Mass data.
They all turned out to be strong IR emitters.
Therefore no obvious candidate for the optical counterpart can be suggested
up to a limiting magnitude of 19.5CR.
In view of the nature of the object (ATEL #156) a negative detection was to
be expected.
This can be cited and/or forwarded to ATEL.
