Sokolov (SAO RAS Niznijh Arkhyz, Russia),\non behalf of a larger colaboration, report:\n\nWe observed an OT (Cucchiara & Fox, GCN Circ. 10606, 10608;\nFilgas, Kruehler & Greiner, GCN Circ. 10607; Landsman & Cannizzo,\nGCN Circ. 10609) of GRB 100414A with the Zeiss-1000 telescope\nof SAO RAS, Russia. Observations started 87.31 hours after\nthe Fermi LAT and GBM triggers (Takahashi et al., GCN Circ. 10594;\nFoley, GCN Circ. 10595). We obtained 12 x 300 sec images both in Rc\nand V bands with the airmass 1.2-1.7 under good weather conditions.\nCalibration was carried out with 8 SDSS nearby stars, whose magnitudes\nwere transformed according to formulae from\nhttp://www.sdss.org/dr5/algorithms/sdssUBVRITransform.html (Lupon 2005).\n\nRc = 21.40 +/- 0.09 (17:39:01 -- 19:05:27 UT, mean epoch = April, 17.765),\nV = 21.75 +/- 0.08 (19:08:49 -- 20:31:05 UT, mean epoch = April, 17.826).\n\nThese magnitudes are not corrected for the expected Galactic extinction\nreported in Landsman & Cannizzo, GCN Circ. 10609.\nThis message may be cited.",
