Lou (THCA) on behalf of the East-Asia\nGRB Follow-up Observation Network (EAFON)report:\n\n\" We have started the observation for the field of GRB 050408 at 17:10\nUT on Apr 08 (55 min after the burst). Using Lulin-One meter Telescope\n(LOT), we have performed 'VR broad band' filter imaging\nobservation. These images show a source in the Swift/XRT error\ncircle. The coordinate is consistent with that of A. de Ugarte Postigo\net al. (GCN 3193). Based on our preliminary 'VR-band' photometry, the\nsource shows variability which decay index is about -0.6 between\n17:17(UT) and 18:33(UT). This source is therefore likely to be the\noptical afterglow of GRB 050408. Further analysis is in progress.\n\nThis message may be cited.\"",
