collaboration:
We observed the field of GRB 050713 (Falcone et al., GCN 3581) with the
Italian TNG telescope, located at the Canary Islands.
The object was observed after twilight, with a seeing of ~1.4", starting
at 5.274 UT (0.8 h after the GRB). A 2-minutes exposure was acquired in
the I filter.
Inside the XRT error circle, we detect one source at the coordinates
(J2000):
alpha = 21:22:09.6, delta = +77:04:29
with an uncertainty of ~1".
We note two further objects lying just outside the nominal XRT error circle:
1: alpha = 21:22:11.8, delta = +77:04:27
2: alpha = 21:22:08.4, delta = +77:04:39
All these object are fainter than the DSS limit, so we cannot confirm if
any of them is related to the GRB. Further analysis is in progress.
