P. Kubanek (IAA-CSIC & GACE), N. Morales (IAA-CSIC), J.L. Ortiz
(IAA-CSIC), A. de Ugarte Postigo (ESO, INAF/OAB), J. Gorosabel (IAA-CSIC),
A.J. Castro-Tirado (IAA-CSIC), M. Jelinek (IAA-CSIC), report on behalf of
a larger collaboration:

We carried out R-band observations of the GRB 090628 XRT position
(Sbarufatti et al., GCN 9586) with the 1.23m Calar Alto telescope. The
observations were done on June 28.9486-29.0225 UT (1.43-3.20 hours post
GRB) with an exposure time of 3120s. A quick inspection of the XRT error
box reveals no object brighter than R ~ 22.
