GCN Circular 14784
Takahiro Nagayama (Nagoya Univ) on behalf of OISTER collaboration. We observed the field of GRB 130606A (Ukwatta et al, GCN Circular 14781) with the Infrared Survey Facility 1.4m telescope and NIR camera SIRIUS at Sutherland Observatory in South Africa. The observation was started with the JHKs bands simultaneously from 2013-06-06 21:38 (UT). We have detected a bright source not detected in 2MASS ALL SKY survey at RA=16:37:35.14 DEC=+29:47:46.4 (J2000) from the first 300sec exposure image. Preliminary photometry results are as follows J=13.1 H=13.9 Ks=14.7 These magnitudes are in the Vega system and not corrected for Galactic extinction in the direction of the GRB.
