We have observed the field of GRB 090113 (Krimm et al.,
GCN 8804) with the 2.5m NOT telescope at Roque de los
Muchachos Observatory (La Palma, Spain). Preliminary
analysis of a 300s R-band exposure with mid time 20:45
UT (2.08h after the burst) does not show any new source
within the enhanced XRT error box (Goad et al., GCN
8809) down to a 3-sigma limiting magnitude of  R > 23.4.
