We have observed the error box of GRB030913 (Suzuki et al., 
GCNC 2383) with MASTER system (http://observ.pereplet.ru) equipped with
new AP16E CCD during the first night after the GRB. 25 frames, obtained
during first 4 hours after the burst, were combined to achieve the better
magnitude limit.

No new sources were detected up to 17.5 unfiltered instrumental magnitude
with S/N ratio of 3.

The part of processed frame is available at
http://ףאהב_קףפבקיפר_ףףשלכץ/מב_כבעפימכץ. North is up, east is left.
Position of possible OT, reported by Guziy et al. (GCN 2391) is marked on
the image. No source brighter than 17.5 is seen there.
