We have observed the 6 sq. degrees field around RXTE-ASM GRB040308 with
MASTER system (355 mm, equipped with AP16E 4k
by 4k CCD.  We obtained 50 unfiltered images with 30s exposure for each.
No afterglow candidate has been found compared to DSS2 within circular
error box 8 arcmin in diameter. Exposures were taken between 18:40 Mar 10
and 20:00 Mar 10 (48 hours after the burst). The estimated limiting
magnitude (S/N=3) is 21.2 .

Preview image of the whole frame in the jpeg format is available at
(center of the error box is signed with a cross)

Reduced FITS images are available by request.
