We have about 50\nunfiltered images of the error box (30s\nexposition, 6 square  degrees field) started at 16 Mar 2005\t21:13:01\nUT (103 s after   GRB time).\nThe limiting magnitude on the images was about 18.0.\nThe JPG-images  of the error box  are available at\nhttp://observ.pereplet.ru/images/GRB050316/2.jpg .\nNo new optical sources with respect to USNO B.\n\nThe triangulation with other Gamma-detectors would be very\nhelpfull because HETE error box rejected.\nThis message may be cited.\n\nThis work is supported by Moscow Union \"Optic\" and partly supported by\nRFFI 04-02-16411.\nMailto: lipunov@sai.msu.ru",
