TITLE: GCN CIRCULAR NUMBER: 8810 SUBJECT: GRB 090113: Observations from NOT DATE: 09/01/14 05:59:12 GMT FROM: Antonio Deugarte at IAA-CSIC A. de Ugarte Postigo (ESO), J. Gorosabel (IAA-CSIC), D. Malesani (DARK/NBI), J.H. Knapen, J.R. Sánchez Gallego (IAC), P. Stiles (Obs. del Sauzal) on behalf of a larger collaboration report 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.
