Hopkins we observed the  \nfield of GRB 060123 (Palmer et al., GCN 4584) both with the PAIRITEL  \n1.3m and the 48\" telescope equipped with Keplercam. At time 25.3 Jan  \n2006 UT we find no significantly new source in i, z, J, H, Ks within  \nthe XRT error circle when compared with SDSS (Cool et al. GCN 4585).  \nImaging in I and z' under better conditions at the Lick 3m + PFCam on  \nMt. Hamilton began at 25.3 Jan 2006 UT: analysis is still in progress  \nbut we confirm the conclusion of Cenko et al. (GCN 4594) that there  \nis no evidence for a new optical source to the SDSS limits.  We do  \nnote that there is a faint (z_AB = 19.87 mag) apparent galaxy (SDSS  \nJ115847.6+453050.8) on the northern outskirts of the 90% containment  \nXRT error circle at J2000: 11:58:47.59, +45:30:50.8.\"\n\nA SDSS-PAIRITEL-PFCam triptych may be found at:\n   http://astro.berkeley.edu/~jbloom/grb060123.ps",
