GCN Circular 11409
GRB 101114A: GROND Upper limits J. Elliott, R. Filgas and J. Greiner (all MPE Garching) report on behalf of the GROND team: We observed the field of GRB 101114A (Swift trigger 438392; Sakamoto et al., GCN #11405) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPI/ESO telescope at La Silla Observatory (Chile). Observations started at 00:42 UT in twilight and just before reaching the 20 deg above horizon telescope limit, on November 16, 48 hours after the GRB trigger, and have total exposure of 425 s in g'r'i'z' and 720 s in JHK. They were performed at an average seeing of 2.5" and at an average airmass of 2.7. We do not detect a source within the Swift-XRT error circle reported by Evans (GCN #11406) down to the following 3 sigma upper limits (all in AB): g' > 21.8, r' > 22.1, i' > 21.7, z' > 21.5, J > 20.3, H > 19.8 and K > 19.2 The given limits are derived based on calibrating the images against GROND zeropoints and 2MASS field stars and are not corrected for the Galactic foreground extinction corresponding to a reddening of E_(B-V)= 0.19 in the direction of the burst (Schlegel et al. 1998).
