TITLE: GCN CIRCULAR NUMBER: 16867 SUBJECT: GRB 140930B: Keck NIR imaging DATE: 14/10/01 11:07:31 GMT FROM: Daniel Perley at Caltech D. A. Perley and J. Jencson (Caltech) report: We imaged the location of short-duration GRB 140930B (De Pasquale et al., GCN 16857) using the Multi-Object Spectrometer for Infrared Exploration (MOSFIRE) on the Keck I 10 meter telescope between 08:44 and 09:04 on 2014-10-01 (UT). We acquired 9 x 35-second exposures in Ks-band and 9 x 44-second exposures in J-band. A faint point-like source is detected at RA=00:25:23.433, dec=+24:17:39.41 (J2000), a location consistent with the afterglow locations previously reported by Evans et al. (GCN 16865) and Tanvir et al. (GCN 16861). Photometry relative to 2MASS gives approximate magnitudes (Vega) of: J = 22.2 +/- 0.2 (tmid = 13.31 hr) Ks = 20.8 +/- 0.3 (tmid = 13.12 hr) We thank M. Kasliwal and T. Prince for the observing time.
