GCN 9027) \nwith Xinglong TNT telescope from Mar.24,14:51:14(UT), \n38.8 hr after the burst. After combined 10*600s R \nband images, the optical afterglow was detected about \nR=20.55 mag at the mean time of 1.651 days after the \ntrigger, with the same calibration star \n(RA = 12 42 39.3, Dec. = +17 05 05.7, Rc=17.15) \nof kann et al., (GCN 9033).\n \nFurther observation is suggested,\nfor the late slowly decay of the optical afterglow.\n\nThis message may be cited.\n\nFor more information about Xinglong GRBs Follow-up\nobservations, please visit the website:\nhttp://www.xinglong-naoc.org/grb/",
