GCN Circular 13479
A. Nicuesa Guelbenzu, S. Klose (both TLS Tautenburg), and J. Greiner (MPE Garching) report on behalf of the GROND team: We observed the field of GRB 120714A (Swift trigger 526593; Saxton et al., GCN 13464) simultaneously in g'r'i'z'JHKs with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPG/ESO telescope at La Silla Observatory (Chile). Observations started at 23:12 UT on 2012-07-14, 15.5 hrs after the GRB trigger, at a airmass of 1.3, and a mean seeing of 1.6". We do not find any source in the XRT error circle (Burrows et al., GCN 13466). Based on an exposure of 1500 seconds in the optical and 1200 seconds in the NIR, at a mean time of 00:00 UT we derive the following upper limits (all AB magnitudes): g' > 23.9 r' > 23.9 i' > 23.1 z' > 23.1 J > 20.9 H > 20.2 Ks > 19.2. The magnitudes are derived based on GROND zeropoints (g'r'i'z') and 2MASS stars (JHK). We note that the Galactic reddening along the line of sight is E_(B-V)= 0.06 mag (Schlegel et al. 1998).
