report:
We observed the HETE-SXC error region of the short/hard GRB 060121
(Arimoto et al., GCN 4550, Prigozhin et al., GCN 4551, Boer et al., GCN
4552) with the 90prime imager on the Steward Observatory 90-inch Bok
telescope at Kitt Peak. We obtained two sets of summed images in Rc, each
with a total exposure time of 1800 seconds, beginning at 04:02:45 UT (5.6
hours after the GRB) and at 05:40:29 UT. Visual comparison of these
images reveals no significantly variable sources to approximately 1.0
magnitudes deeper than the SDSS r' image (Cool et al., GCN 4554).
