GCN 6932, Sato et al. GCN 6933) \nwith the TNT 0.8m telescope at Xinglong Observatory started \nfrom 19:05:11.203 UT, about 0.435 days after the trager of the \nburst.  A set of 15*600s R-band images were obtained. \nIn our 15*600s combined image, we found two clear new objects\nat the position RA(J2000) = 10;58:11.3 Dec(J2000)=+53:50:56 and \nRA(J2000)= 10:58:21.459 Dec(J2000)=+53:51:09.85 within the error \nregion of the BAT (GCN 6933), based on the USNO-B1.0 \nwith uncertainties of 3\" in both coordinates, respectively. \n\nAfter psf photometry, we estimated that the magnitudes of \nthe new two objects were about 21.49+-0.220, 21.46+-0.227  reletive to \nUSNO-B1.0 stars, respectively, with the mean time 0.486 days after \nthe burst.\n\nWe could not confirm that which one of the two new objects was the OT\nof the burst or maybe thay were not al all but one of them \nwas possible to be.\n\nWe suggest new observations will be going.\n\nMore detailed analysis is on going!\n\nThe message my be cited\n\n[GCN OPS NOTE(19oct07): Per author's request, The Subject-line\nwas changed from \"20070521\" to \"071018\".
