Sakhibullin (KSU)\n\nreport:\n\n  We observed the afterglow of GRB 040924 (Fenimore et al. GCN 2735, Fox \nand Moon, GCN 2734) with Russian-Turkish 1.5-m telescope (Bakyrlytepe, \nTUBITAK National Observatory, Turkey). We made 33x300s images in R between \nSep. 25, 23:45 UT, and Sep. 26, 2:45 UT. The observations were hampered by \nthe bright-moon and bad seeing (1.7 arcsec). The object was clearly \ndetected near the limit of the combined image. We estimate its magnitude \nto be m_R=23.7+/-0.2.\n\nThis magnitude is consistent with power law decay with index -1.16, \nobtained in our previous observations (GCN 2749). The KAIT earlier \nmeasurements (GCN 2748) seem to be consistent with this power law as well. \nTherefore, to the first approximation, the whole light curve of the GRB \n040924 afterglow can be described as a single power law with index -1.16.\n\nThe combined light curve can be found at:\n\nhttp://hea.iki.rssi.ru/~rodion/040924/lc_all.jpg\nor\nhttp://www.tug.tubitak.gov.tr/~irekk/grb/grb040924/lc_all.jpeg\n\nThe finding charts:\n\nhttp://hea.iki.rssi.ru/~rodion/040924/fcharts.html\nor\nhttp://www.tug.tubitak.gov.tr/~irekk/grb/grb040924/fcharts.html\n\nThis message may be cited.",
