TITLE: GCN GRB OBSERVATION REPORT NUMBER: 1112 SUBJECT: GRB011019: Optical observations DATE: 01/10/20 11:32:03 GMT FROM: Paul Price at RSAA, ANU at CIT P.A. Price, B.P. Schmidt, T.S. Axelrod (RSAA, ANU) and D.W. Fox (Caltech) report: "We have observed the centre 40 arcmin square region of the error box of GRB 011019 (GCN #1109) with the robotic 50-inch telescope at Mount Stromlo Observatory, commencing at 2001 Oct 20.39 UT. Our combined 3x300 sec images in MACHO R band have a limiting magnitude of approximately R ~ 19.5 mag. Neither automated or manual comparison of the images with the Digital Sky Survey reveal the presence of an optical transient. Further observations are planned." This message may be cited.
