of larger GRB follow-up collaboration:
We observed the field of the GRB 141031B (Gompertz et al., GCN 16998)
with Zeiss-1000 (East) 1m telescope of Tien Shan Astronomical
Observatory on Oct., 31 starting on (UT) 15:39:02. Within enhanced XRT
error circle (Goad et al., GCN 17009) we do not detect any object
either in a single image (Mazaeva et al., GCN 17007) or in combined
image of a total exposure of 4800 s.
Details of the photometry are following:
