MASTER (http://observ.pereplet.ru) responded to GRB 050801 (Swift
trigger 148833, GCN 3752). The first image was at 198 sec after SWIFT
GRB050803 detection (19:14:00.34 UT) under the bad weather
conditions on the evening sky near the horizont (GCN3750). We have the
first low resolution spectra (50A) image of the error box by 200 mm
camera up to 9m.
The first unfiltred image on 355 mm camera was made at 28 min
(19h32m25s UT) after GRB time due to technical problems (the limit is
14.6 m).
The magnitude close to R.
