larger GRB follow up collaboration report:

We have observed the error box of the Swift GRB060323 (Vetere et al., GCN
4904) with 0.4m telescope of  Ussuriysk Astrophysical Observatory (UAPhO) in
R-band between  Mar. 23 (UT) 15:00 - 15:51.  We do not detect the optical
afterglow (Covino et al., GCNs 4911, 4916), and upper limits of combined
images calibrated against  of USNO-A2.0 (R) are following:

Mid time,    Exposure,   Limiting mag.
