We observed the error box of GRB060923C (Stamatikos et al., GCN 5591)
with 0.4m telescope of Ussuriysk Astrophysical Observatory in R-band
starting Sep.23 (UT) 13:51:55. We do not detect the optical transient
detected by Fox (GCN 5607). Upper limits of the first image (exposure 60 s)
and combined image (exp. 10x60 s) are based on USNOA2.0:
Mid time, Exposure, Limiting mag (3 sigma)
(UT) (s)
Sep. 23.5781 1x60 16.0
