TITLE: GCN CIRCULAR NUMBER: 7984 SUBJECT: GRB 080714: GROND confirmation of the optical/NIR afterglow DATE: 08/07/16 06:43:03 GMT FROM: Thomas Kruehler at MPE/MPI T. Kruehler, J. Greiner, C. Clemens, A. Yoldas (all MPE Garching), A. Kupcu Yoldas (ESO) and G. Szokoly (Eoetvoes Univ., Budapest) report on behalf of the GROND team: We observed the field of GRB 080714 (Swift trigger 316910; M. Perri et al., GCN #7978) in two epochs, simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2m ESO/MPI telescope at La Silla Observatory (Chile). We detect the optical afterglow reported by Marshall & Perri (GCN #7982) at RA (J2000.0) = 13h 32m 25.49s DEC (J2000.0) = -60d 16' 39.3" with an absolute uncertainty of 0.6". Preliminary photometry yields the following magnitudes against USNO-B1 and 2MASS field stars in stacked images: Band T_mid(h) Exp(min) Mag g' 6.4058 50 > 24.3 g' 30.3847 32 > 23.4 r' 6.4058 50 22.76 +- 0.08 r' 30.3847 32 > 23.6 i' 6.4058 50 21.15 +- 0.07 i' 30.3847 32 22.68 +- 0.24 z' 6.4058 50 20.39 +- 0.06 z' 30.3847 32 21.82 +- 0.29 J 6.2827 40 18.58 +- 0.11 J 30.2958 30 20.00 +- 0.16 H 6.2827 40 17.25 +- 0.14 H 30.2958 30 18.52 +- 0.24 not corrected for the expected Galactic foreground reddening of around E(B-V) = 1.15 mag (Schlegel et al., 1998). Given the high foreground extinction, the non detection in g' is consistent with the powerlaw slope of the broad band SED derived from r to H and does not necessarily imply a high redshift. Additionally, we note the presence of a nearby, faint (r'~ 24.1 +- 0.2) source at RA (J2000.0) = 13h 32m 25.60s DEC (J2000.0) = -60d 16' 37.7" roughly 1.8" away from the afterglow, which may influence the photometry in the second epoch.
