Moskvitin (SAO RAS) report on behalf of larger GRB follow-up\ncollaboration:\n\nThe field of GRB 150518A (Kawamuro et al.,  GCNC 17825; Sbarufatti et al.,\nGCNC 17827) was observed with the Zeiss-1000, 1-m telescope of SAO RAS.\nThe observations were carried out on the May, 19, 20:10:25 -- 21:26:30 UT\n(T - T0 ~ 23 hours). 12 x 300 sec frames in Rc filter were obtained.\n\nWe clearly detect the source mentioned by the other teams (Xu et al.,\nGCNC 17829, 17832; Mao et al., GCNC 17830; Littlejohns et al., GCNC 17831).\nThe magnitude of the object is R = 21.2 +/- 0.1 is almost equal\nto the magnitude of SDSS J153648.25+161946.9 (within the errors),\nprobable host galaxy of GRB, so we can not find a significant excess from\nthe\npossible OT.\n\nPhotometry is based on the nearby stars, whose SDSS magnitudes were\ntransformed to UBVRI system. The magnitude of object is not corrected\nfor the Galactic extinction.",
