TITLE: GCN GRB OBSERVATION REPORT NUMBER: 5148 SUBJECT: GRB 060515: NIR observation DATE: 06/05/19 07:52:04 GMT FROM: Yuji Urata at Saitama U Y. Urata (Saitama-U), K.Y. Huang, W.H. Ip (NCU) report on behalf of EAFON team: "We have imaged the GRB 060515 field (Cummings et al., GCN 5132) with J and Ks band using CFHT/WIRCam. The observation started from 3.18 hours after the trigger. There is no new sources in the XRT error circle (Page et al, GCN 5139) to a limiting magnitude of J > 20.0 and Ks > 18.9 derived from several 2MASS objects in the fields. The possible TAROT afterglow (Klotz, Boer, and Atteia, GCN 5134) do not appear in our J and Ks band images to the same limiting magnitude. ---------------------------------------- Time(mid) Exp Filter Limit (SN=3) ---------------------------------------- 3.23 h 20s x 7 Ks >18.9 3.34 h 20s x 7 J >20.0 ---------------------------------------- We thank Dr. Cabanac, Dr. Loic, Dr. Wang and the staff of QSO team."
