TITLE: GCN CIRCULAR NUMBER: 6361 SUBJECT: GRB 070429A: optical and NIR observations DATE: 07/04/29 13:31:00 GMT FROM: Antonio Deugarte at IAA-CSIC A. de Ugarte Postigo, A.J. Castro-Tirado, M. Jelinek, P. Kubanek, R. Cunniffe, S. Vitek, J. Gorosabel (IAA-CSIC), I. Skillen (ING) L. Sabau-Graziati (INTA) report: Robotic observations from the 0.6m BOOTES-IR telescope in R and z bands started at 3:50 UT (3.25 hours after the burst), as soon as the object became visible from the observatory. No source is detected inside the XRT error box. We have observed the field of GRB 070429A with the 4.2m WHT+LIRIS in J, H and K bands starting at 05:44:00 UT (4.148 hours after the burst). Preliminary reduction of the K-band data shows a faint source at the following coordinates (J2000 +/- 1"): R.A.: 19:50:48.90 Dec.: -32:24:17.0 A finding chart can be found at: http://www.iaa.es/~deugarte/GRBs/070429A/GRB070429A.gif Further analysis to check variability and colour of this source is ongoing.
