(GCN 2870) at Lulin (Taiwan, 1-m telescope)\nand XingLong (China, 0.8 m telescope) Observatory. The R band\nobservations are summarized as below:\n\n Start Time (UTC)   Filter      Exposure (sec)  Limit mag.   Site\n                                                 (SN=3)             \n  Dec. 9.47           R       300 x 2 + 600 x 2   >~ 21      Lulin\n  Dec. 9.48           R       300 x 1 + 360 x 1   >~ 20      XingLong\n \nLimiting magnitudes were estimated by comparison with several\nUSNO-B1.0 stars. The candidate was not detected brighter than the\nlimiting magnitudes.\"\n\nThis message may be cited.",
