2,8 hours after SWIFT alert (GCN 2984) MASTER robotic
telescope (http://observ.pereplet.ru) had imaging the
corresponding area of the sky under the bad weather conditions on the
evening sky. We have
about 15 unfiltered images of the error box (45s exposition, 6 square
degrees
field) started at 26 Jan 2005 14:49:18 UT (2,8 hours after GRB time).
The better limiting magnitude on the images was about 15.5 (close to
R-band).
There is no OT within the 1' SWIFT error circle on 3 sigma level.
On the some of the images (around 15h 18m UT) we see (in the 1' SWIFT
error circle) very close
to noise one object
with coordinates
18 32 28.5
+42 21 47
(error = +-4'')
The optical limit on summ - 16.5.
