TITLE: GCN CIRCULAR NUMBER: 10461 SUBJECT: GRB 1000302A : A possible afterglow candidate DATE: 10/03/02 23:19:23 GMT FROM: Kuiyun Huang at ASIAA GRB 1000302A : A possible afterglow candidate K.Y. Huang (ASIAA), H.Y. Hsiao, and Y. Urata (NCU) on behalf of the EAFON team. We took several R and I band images for the GRB 1000302A field (Cummings et al. GCN 10458) with Lulin 1-m telescope in Taiwan. The observations started at 16 mins after the bursts. Our R-band combined image (300sx5) shows a marginal source (R~ 21) in the XRT error circle. However, the source is clearly detected (I~ 19.9) in our single I(300s)-band image taken around 44 mins after the burst. No observations will be made with LOT becasue of morning twilight. Further deep observations are encouraged to confirm variability of this candidate. The brightness of the candidate were calibrated with a nearby USNOB star. This message can be cited
