Gamma-ray Bursts (GRBs) have been enigmatic phenomena for more than three decades since it discovery. In 1997,the first GRB (GRB970228) optical counterpart was observed, detection of transient optical emission associated with bursts become more important. In recent years, a breakthrough in GRB study have been brought about by discovery of X-ray and optical afterglow in several events, which then lead to the identification of their red-shift and host galaxies.
We started GRBs follow-up observation by using Lulin 1-m telescope (LOT) since July 2003.We plan to discover the optical counterparts for GRBs and do multi-band observations to understand the temporal and spectral evolution of afterglow. There are four events were observed until now. Three events are upper LOT limiting magnitude, one candidate was observed of GRB031203 event. By LOT follow-up bservation of this candidate, the variability of light curve is small. The position of the candidate is almoxt the same as radio afterglow and Bloom et al (2003) observed our candidate and determine it was a host galaxy. So our candidate might be the host galaxy.
