Y. Qiu (BAO) on behalf of RAFON report:

"The 0.8-m telescope at Xinglong Observatory, China and 1.0-m
telescope at Lulin Observatory, Taiwan started to observe GRB 060210
afterglow (Fox et al. # 4723; Li #4725) at 10.73 UT (~ 5.75 hours
after burst) and 11.07 UT (~6.08 hours), respectively. No source was
detected at afterglow position of our R and I images. Compare with
USNO-B1.0, 3-sigma limiting magnitude are summarized as below :
