The first image was started at 17h13m34s UT. Now we have 50 unfiltered images of the error box (45s exposition, 40 x 50 arcmin, 200 mm camera). Ther is no optical transient up to 18.5 m at position given Fox and Moon (GCN2734). Our unfiltered magnitude is close to R filter. So, we conclude that OT proposed by Fox and Moon can be real optical emission from GRB040929. Sum FITS image are available at http://observ.pereplet.ru/images/GRB040924/ This message may be cited.
