on behalf of a larger collaboration:
"We carried out R-band observations of the GRB 090529 XRT error circle
(Sakamoto et al. GCN 9430; Osborne et al. GCN 9433) with the 1.5m OSN
telescope. On May 29.87-29.93 UT (0.27-0.33 days afer the GRB) we detected
the optical afterglow (Xin et al. GCN 9431) at R=21.44+/-0.06, against the
same reference star used by Kann et al. (GCN 9436)."
