After SWIFT alert (GCN 2951) MASTER robotic
telescope (http://observ.pereplet.ru) had imaging the
corresponding area of the sky under the bad weather conditions. We have
50 unfiltered images of the error box (45s exposition, 6 square degrees
field) started at 17 Jan 2005 14:58:40 UT (2 hours after GRB time).
The limiting magnitude on the summ of the best 10 images was about 19.0.
There is no OT within the 0'5 SWIFT error circle.
The central part of the JPG-images are available at
