Gogus (Sabanci Uni.)\n\nreport:\n\nWe observed the GRB 080810 afterglow with Russian-Turkish 1.5-m telescope\n(RTT150, Bakirlitepe, TUBITAK National Observatory, Turkey).\n\nThe serie of 600 sec (Ic), 600 sec (Rc), 900 sec (V) exposures was made\nby using TFOSC  instrument under moderate seeing, starting at 12 Aug 2008,\n01:19 UT, i.e. 36.16 hours after the burst.\n\nThe OT is clearly detected on all images. Using USNO-B1.0 stars\nwe estimate an Rc magnitude of 20.66+/-0.03 (~36.4 hours after the burst).\nUsing our earlier observations (Burenin et al., GCN8088)\nthe calculated power law index is -0.91+/-0.09 for decay\nfrom ~8.3 h to ~36.4 h.\n\n\n-- \nThis message has been scanned for viruses and\ndangerous content by MailScanner, and is\nbelieved to be clean.",
