TITLE: GCN CIRCULAR NUMBER: 16435 SUBJECT: GRB 140622A: GROND Upper limits DATE: 14/06/22 18:07:36 GMT FROM: Corentin Delvaux at MPE M. Tanga, C. Delvaux and J. Greiner (all MPE Garching) report on behalf of the GROND team: We observed the field of GRB 140622A (Swift trigger 602278; D'Elia et al., GCN #16433) simultaneously in g'r'i'z'JHK with GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2 m MPG telescope at ESO La Silla Observatory (Chile). Observations started at 09:40 UT on June 22, 2014, 0.07 hours after the GRB trigger. They were performed at an average seeing of 1.3 and at an average airmass of 1.23. We do not detect a source within the Swift-XRT error circle reported by D'Elia et al. (GCN #16433) down to the following 3-sigma AB magnitudes: g' > 24.3 mag, r' > 24.3 mag, i' > 24.1 mag, z' > 24.1 mag, J > 21.3 mag, H > 20.9 mag, and K > 19.4 mag. We report the detection of a faint object at the border of the 2.6" Swift-XRT error circle at coordinates RA(J2000) = 21:08:41.73 Dec(J2000) = -14:25:06.5 This object is detected in g', r', i', z' and J and there is no evidence of fading. Its estimated AB magnitudes are g' = 23.4 +/- 0.2 mag, r' = 23.4 +/- 0.2 mag, i' = 22.5 +/- 0.1 mag, z' = 22.2 +/- 0.1 mag, and J = 20.9 +/- 0.3 mag. At this time, we cannot assert that this object is the host galaxy of GRB 140622A. The given limits and magnitudes 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)= 0.07 mag in the direction of the burst (Schlegel et al. 1998). [GCN OPS NOTE(22jun14): Per author's request, the Subject line was corrected from "140422A" to 140622A".]
