Sakhibullin (KGU)\n\nreport:\n\nThe INTEGRAL error circle of GRB 040827 (GCN 2672) was observed by\nRussian-Turkish 1.5-m telescope (Bakyrlytepe, TUBITAK National Observatory,\nTurkey). We made 17x100s R band images, starting at 17:30UT, 5:40 after the\nburst. Due to bad seeing (2''), extremely large zenith distance (60--80\ndegrees), partially cloudy sky and very bright moon the combined image is\nonly slightly deeper than DSS2. We detected no new objects as compared to\nDSS2 red plate.\n\nWe do not confirm optical transient reported by Lipunov et al. (GCN\n2676). \n\nThere is also nothing at the position of XMM X-ray source (GCN 2678) down to\nthe limit of our combined image, i.e. to approximately 20.5 mag. More exact\nlimit will be obtained after when our image will be calibrated\nphotometrically.\n\nThis message may be cited.",
