We observed the field of GRB 160123A (Malesani et al., GCN 18926) using
the LCOGT-1m located at the Siding Spring Observatory. We obtained
20x150s R-band images, starting at 12:04:41 UT on 2016-01-23, i.e.,
3.106 hr after the burst.
No optical source is detected at the enhanced XRT position of this GRB
(Beardmore et al., GCN 18927), down to a limiting magnitude of R~21.0
mag, calibrated with nearby USNO B1 stars.
