report:

" We observed the error region of GRB 060116 (Campana et al., GCN
4519Loading...
 
 ) using 1-m telescope at Lulin Observatory, Taiwan. After the
twliglights, the I and R band observations were started at 11.16 UT(
about 2.9 hours after burst). No variable source was detected in the
BAT and XRT error region(Campana et al. GCN 4522Loading...
 
 ) at our co-add I and
R images.  The limiting magnitude of I and R band were calibrated
against USNO-B1.0 catalog (I and R, respectively).
