TITLE: GCN CIRCULAR NUMBER: 8366 SUBJECT: GRB 081012: Observations from NOT DATE: 08/10/13 01:25:26 GMT FROM: Antonio Deugarte at IAA-CSIC A. de Ugarte Postigo (ESO), D. Malesani (DARK/NBI) T. Augusteijn (NOT) report on behalf of a larger collaboration: We have observed the field of GRB 081012 (Stroh et al., GCN 8361) from the 2.5m NOT telescope at Roque de los Muchachos Observatory. A combination of 6x300s R-band observations with mean time 23.79 UT (0.44 days after the burst) did not show any source within the XRT error box (Kennea & Stroh GCN 8364) down to a 3-sigma limiting magnitude of R > 22.0. The images were moderately contaminated by the light of the nearby Moon. We thank the student group from the Mikkeli high school (Finland) for help in carrying out the observations.
