TITLE: GCN CIRCULAR NUMBER: 6168 SUBJECT: GRB 070223: NIR observations at WHT DATE: 07/03/06 16:49:26 GMT FROM: Alberto Castro-Tirado at Inst.de Astro. de Andalucia A.J. Castro-Tirado, A. de Ugarte Postigo, M. Jelinek, J. Gorosabel (IAA-CSIC), J. Licandro and D. Bramich (ING La Palma), report: "We have observed the XRT position of GRB 070223 (Vetere et al. GCN 6130) with the 4.2m WHT (+LIRIS) telescope at the Spanish Observatorio del Roque de los Muchachos in La Palma. The observations were carried out in the JHK-bands starting on Feb 23.165-23.195 UT. We detect a faint object in all bands consistent with the one reported by Mirabal et al. (GCNC 6162) and also with the XRT position given by Vetere et al. Further imaging is required to confirm if this is the NIR afterglow to GRB 070223." This message can be quoted.
