  "body": "We observed the afterglow (Oksanen, GCN 6873) of GRB 071010B\n(Markwardt et al., GCN 6871) with the EST 1m telescope at\nXinglong Observatory started from 19:07:59(UT) Oct.11. Totally\n11*600s V-band images were obtained. With the calibration data\nreported by Henden (GCN 6909) we derived the afterglow had \na magnitude V=20.75 +/- 0.05 with mid-time 23.314 hours \nafter the burst.\n\nCompared with the V-band magnitude of Daniel Kocevski \n(GCN 6919), we found the V-band magnitude of the afterglow\ndecayed deeply about 1 magnitude after about 5 hours. \n \nThis message may be cited.",
