TITLE: GCN GRB OBSERVATION REPORT NUMBER: 3595 SUBJECT: GRB 050713A : Lulin R-band observation DATE: 05/07/13 16:04:27 GMT FROM: Yuji Urata at RIKEN Z.Y. Lin, K.Y. Huang, W.H. Ip (NCU), Y. Urata(RIKEN), Y. Qiu (BAO), Y.Q. Lou (THCA) on behalf of EAFON report: "We have imaged the GRB 050713A afterglow position (Malesani et al.; Hearity et al.; Guziy et al.; and Monfardini et al.) at 10.3 hours after the burst using Lulin 1-m telescope. The afterglow was not detected in our R band co-add image (300s x 5 frames). Compare with USNOB1.0 stars, we estimate the afterglow would be fainter than 22.4 mag during our observations.
