We observed the field of GRB 150423A (Pagani et al., GCN 17728Not found
 
 
) with the 2.4-meter optical telescope at Gao-Mei-Gu (GMG) station of Yunnan Observatory. Observations began from 17:11:14 UT, May 2nd, 2015, about 9 days after the trigger. We did not
detect any source / rebrightening feature at the afterglow position down to a limit of z~21.0 mag with poor observational condition.
