Valeev\n(SAO-RAS Niznijh Arkhyz, Russia),\non behalf of a larger colaboration, report:\n\nWe have observed the field of GRB090618\n(Page et al., GCN 9706) with the 1-m telesecope\nof the SAO RAS in Caucasus. Within the XRT error\ncircle (Page et al., GCN 9707) we detected one\nobject which not present in the DSS. The object's\ncoordinates are:\n    R.A. (J2000.0) = 16:34:43.044\n    DEC. (J2000.0) = +72:53:04.82\nwith uncertainty about 0.5 arcsec. Using\nthe USNO A2.0 star 1628-0121951 (R2=14.51)\nas a calibration we estimated the object's\nbrightness as following:\n\n   R_mag         exp.(sec)       mid.time\n                             (sec after the trigger)\n18.26 +/- 0.05     60              2126\n18.39 +/- 0.05     60              2252\n18.33 +/- 0.05     60              2344\n18.71 +/- 0.05    120              3183\n18.97 +/- 0.05    180              4296\n19.17 +/- 0.06    180              5492\n19.28 +/- 0.07    240              6089\n19.55 +/- 0.12    300              6824\n\nAccording to its variability we concluded that\nthe detected object is the OT of the GRB090726.\n\nFurther analysis are ongoing.\n\nThis message may be cited.",
