TITLE: GCN GRB OBSERVATION REPORT NUMBER: 4968 SUBJECT: GRB060418 : LT optical afterglow observation DATE: 06/04/18 03:46:33 GMT FROM: Andrea Melandri at Liverpool John Moores U A. Melandri, A. Gomboc, C.G. Mundell, C. Guidorzi, A. Monfardini, C.J. Mottram, R.J. Smith, I.A. Steele, D. Carter, M. Burgdorf, S. Kobayashi, D. Bersier, M.F. Bode (Liverpool JMU) report: "The 2-m Liverpool Telescope immediately observed the field of GRB060418 (Falcone et al. 4966) and started observing its position about 5.0 minutes after the GRB. The automatic "detection mode" procedure clearly detected the optical afterglow candidate at the XRT position reported by Falcone et al. (GCN 4966). This source has a R magnitude of ~14.0 after ~6 minutes from 3x10-s images and clearly show a rapid early optical decay. Further analysis and observation are still ongoing."
