We observed the localization of the Swift GRB090726 (Page et
al., GCN 9706) with the 50 cm telescope in Ondrejov (Czech
Republic), starting at 22:45:41 UT, i.e. 194s after the GRB

We clearly detect the afterglow reported by Moskvitin et al.
(GCN 9709) in its rising phase on the first image with
magnitude ~ 18.3 (same calibration as GCN 9709).
