Fox \n(Penn State) report:\n\nWe obtained imaging and spectroscopy of the field of the short GRB 141212A \n(Ukwatta et al., GCN 17158) using GMOS on the 8 m Gemini-North telescope \nstarting at 04:35 UT on 13 December, 16.4 hours after the BAT trigger.\nIn 5x180s of i-band imaging with 0.5\" seeing, all three objects found by \nMalesani et al. (GCN 17170) are well detected.  Using an archival calibration, \nwe measure i=22.2 +/- 0.1 mag for object A, the extended object present inside \nthe enhanced XRT error circle (Osborne et al., GCN 17164).\n\nIn addition, we oriented a spectroscopic slit through both extended objects A \nand B (using the terminology of Malesani et al.).  We obtained 2x900s of \nspectroscopy with the R400 grating covering the wavelength range 5890-10100 \nAngs.  Both galaxies exhibit prominent nebular line emission from [O II], \nH-beta, and [O III].  Galaxy A, the likely host, has a redshift of z=0.596, \nwhile Galaxy B has a redshift of z=0.672.",
