We observed GRB 121226A (Swift trigger 518731, Krimm et al. 2012, GCNC
14105) field with the 1.04m telescope at ARIES, Nainital starting at
2012-12-26

time 
of 300 sec each, were obtained.

Within the XRT error-circle, we do not detect any optical source down to 
following limiting magnitudes.

Dec 26.9118 UT, 300sx4, I_c ~ 18.8 mag
Dec 26.9292 UT, 300sx6, R_c ~ 19.5 mag
