TITLE: GCN CIRCULAR NUMBER: 9614 SUBJECT: XRF 090702 : RTT150 optical observations DATE: 09/07/05 01:59:06 GMT FROM: Alexander Meshcheryakov at IKI A. Meshcheryakov (IKI), I. Khamitov (TUG), R. Burenin, M. Pavlinsky, R. Sunyaev (IKI), Z. Eker (TUG), U. Kiziloglu (METU), E. Gogus (Sabanci Uni.), I. Bikmaev, N. Sakhibullin (KSU/AST) report: We observed the field of XRF 090702 detected with IBIS/INTEGRAL (Paizis et al., GC N 9603;) with Russian-Turkish 1.5-m telescope (RTT150, Bakirlitepe, TUBITAK National Observatory, Turkey), starting at 02 Jul, 18:54 UT, i.e. 8.2h after the burst. We made 2x600s exposures in SDSS r filter. In the combined image we do not detect any sources inside the XRT/SWIFT error circle (Sbarufatti & Mangano, GCN 9604). Using SDSS catalog for photometric calibration, we estimate 3-sigma upper limit for any optical counterpart as m_r > 22.4.
