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.
