Hiroyuki Maehara (Univ. of Tokyo) reports on behalf of the OISTER collaboration:
We observed the field of GRB 140629A (Lien et al. GCN 16477) with the 1.05-m
Schmidt telescope and KWFC (Sako et al. 2012, Proc. SPIE 8446, 84466L) at
Kiso Observatory in Japan. The observations were made in the Sloan z-band at
2014-06-29 14:30-14:39 (UT; 13-22 min post burst) and 16:30-16:45 (133-148
min post burst).
We detected an uncatalogued fading source at RA=16:35:54.45, DEC=+41:52:36.6
(equinox 2000.0; uncertainty 0".3).$B!!(BPreliminary photometry of the source
is as follows:
obs. date (mid time) t-T0 (days) exp.(sec) filter mag limiting mag

16:45:18 0.1026 180 z 17.87+/-0.08 18.9
The photometry is based on z-mag of SDSS stars in the observed field.
