�We have obtained deep r�i�z� images with the 10.4m GTC telescope at
Observatorio del Roque de los Muchachos for GRB 121226A (Krimm et al. GCNC
14105; Baumgartner et al. GCNC 14111) starting on Dec 27.230--27.261 UT
(i.e., 10.3--11.1 hr post burst). A faint object is detected at
RA(J2000)=11:14:34.14, DEC(J2000)=-30:24:22.9 (0.7" error in each
coordinate), consistent with the position of the X-ray afterglow
(Littlejohns et al. GCNC 14112). The object shows a magnitude around
r'~25. At this stage we cannot conclude whether this is the GRB 121226A
optical afterglow or the underlying host galaxy.�
