TITLE: GCN CIRCULAR NUMBER: 14671 SUBJECT: GRB 130515A: IRSF NIR Observation DATE: 13/05/17 08:07:22 GMT FROM: Daisuke Kuroda at OAO/NAOJ Takahiro Nagayama (Nagoya Univ.) and Shogo Nishiyama (NAOJ) on behalf of OISTER collaboration. We observed the field of GRB 130515A (David Palmer, GCN Circular 14650) with the Infrared Survey Facility 1.4m telescope and NIR camera SIRIUS (Nagayama et al., 2003) at Sutherland Observatory in South Africa. The observation was made with the JHKs bands simultaneously from 2013-05-15 01:26 (UT), 5 minutes after the BAT trigger, to 04:41. We have also detected the source detected by VLT (Dong Xu, GCN Circular 14653) and GROND (Sebastian Schmidl, GCN Circular 14650) at RA=18:53:45.79, DEC=-54:16:47.1 (J2000). Preliminary photometry results are as follows All combined images (Total exposure time: 154 min, 2013-05-15 01:26 - 04:41) J = 20.1 ± 0.2 H = 18.6 ± 0.2 Ks =18.7 ± 0.3 First 120 images (Total exposure time: 60 min, 2013-05-15 01:26 - 2:45) J = 19.4 ± 0.2 H = 18.9 ± 0.2 Ks: Non detection These magnitudes are in the Vega system and not corrected for Galactic extinction in the direction of the GRB.
