TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2151 SUBJECT: GRB030418: Kiso near infrared observations DATE: 03/04/18 17:21:50 GMT FROM: Yuji Urata at RIKEN <urata@crab.riken.go.jp> H. Mito, S. Nishiura and Y. Urata on behalf of the Kiso GRB team: " We have observed the field of GRB030418(=H2686) using the Kiso observatory 1.05 m Schmidt telescope with near infrared camera KONIC. The KONIC has circular field of view with 8.5'radius. We started to observe the center region of HETE S/C_Update (Seq_Num 2) with J, H, Ks band at 21 min after the burst. The afterglow reported Price et al. (GCN2148) is out of these images. We re-pointed to the field including the afterglow position at 69 min after the burst, . We obtained five J-band images with 300 s exposures. We could not identify the afterglow with the limiting magnitude J ~ 13 (3 sigma) at the 69 min after the burst. We estimated it comparison with 2MASS J1054356-070118. The more accurate analysis are in progress." This message may be cited.
