TITLE: GCN CIRCULAR NUMBER: 4588 SUBJECT: GRB 060124 : Optical observation at Xinglong and Kiso DATE: 06/01/25 04:56:49 GMT FROM: Yuji Urata at RIKEN C.K Lu, Y. Qiu (BAO), Y.Q. Lou (THCA) Y. Urata (RIKEN), K-Y Huang (NCU) on behalf of EAFON report: GRB 060124 : Optical observation at Xinglong and Kiso "We started R and I band imaging observation of GRB 060124 field at 16:21 (UT) using 0.8-m telescope at Xinglong observatory, China. The OT reported by (Kann # 4577) was detected clearly at RA = 05:08:25.9 Dec +69:44:27. The I band image is available at http://cosmic.riken.jp/grb/eafon/GRB060124_Xinglong_Iband.jpg Based on our preliminary R and I band photometry for Xinglong data, the OT light curve do not show clear decay in our observational phase. We have also checked R-band data obtained under bad seeing condition at Kiso observatory (Tomita et al. #4575). Due to contamination from nearby bright star (USNOB: 1597.0077413), it is hard to identify the OT by visual inspection. However, we also found the OT in Kiso R band images." This message may be cited.
