Torii (Osaka U.) reports: The error region of GRB 060110 (Zane et al. GCN 4463) was observed by a 0.3 m telescope in the New Mexico Skies Observatory. Starting at 08:03:39 UT (142 s after the burst), several 120 s exposures in Ic and Rc bands were obtained. Preliminary analysis of the two Ic frames does not reveal an afterglow candidate brighter than about 16 mag (USNO B1.0 I mag) within the BAT error region. ===
