This camera is \non one mount with is more large MASTER telescope. These observation have \nbeen received during the regular  sky survey. Directly at the moment of \nGRB the telescope had repointing, so sets since 3 seconds before grb to 3 sec. after grb time (2010-05-17 12:26:24 UT) is moved.\n\nThe magnitude limit of the each good image is  ~ 8-m at the center of FOW, \nand ~ 4-5 m on each moved image.\n\nOur unfiltered images are calibrated relative to Tycho stars (V).\n\nSpecification of coordinates is required.\n\nImages available here:\nhttp://observ.pereplet.ru/images/GRB100517A/after.jpeg\nhttp://observ.pereplet.ru/images/GRB100517A/before.jpeg\n\nThe message may be cited.\n\nmailto: lipunov@sai.msu.ru",
