report on behalf of a larger collaboration:

We used the 1.23m CAHA telescope to image the XRT source (Benardini et al.
GCN 17251) detected in the GRB 141229A field (Fujita et al. GCN 17246;
Evans et al. GCN 17247; Roberts et al. GCN 17249). The observations were
carried out in the I-band starting on Dec 29.93278 UT (~10.6 hours post
GRB). No object brighter than I~21 (Vega) is detected within the XRT error
circle.
