Kouprianov (GAO), A.\nPozanenko (IKI)  on behalf of larger GRB follow up collaboration report:\n\nWe observed the afterglow of GRB070208  (Guidorzi et al., GCN 6077, Fox et\nal., GCN 6078, Bloom GCN  6079) in R-band on Feb.8 with 1.5m telescope of\nSayan observatory. A set of 300 s exposures was obtained between  (UT) 15:43\nand 19:28 (Klunko et al., GCN 6093). Best combined image of total exposure\n4200 s is centered at Feb. 7.785. After mask subtraction of the nearby\ngalaxy in the best combined image we estimate OT magnitude as following:\n\nMid time (UT), Exposure,  R_mag\nFeb. 7.785     14x300 s   21.4 +/- 0.2\n\nThe photometry is  based on USNO A2.0 stars. The mask subtracted image can\nbe found in http://grb.rssi.ru/GRB070208/\n\nThe message may be cited.",
