TITLE: GCN CIRCULAR NUMBER: 6840 SUBJECT: GRB 071003 Optical observations DATE: 07/10/03 17:50:25 GMT FROM: Kuntal Mishra at ARIES,Nainital,India K. Misra, S. B. Pandey, Rupak Roy (ARIES, NainiTal, India) and Alberto J. Castro-Tirado (IAA, Granada) on behalf of larger Indian GRB collaboration The Swift GRB 071003 (Schady et al. GCN 6837) was observed using 1.04 m Sampurnanand Telescope. The optical afterglow candidate reported by Li (GCN 6838), Cenko & Fox (GCN 6839) is clearly seen in U and B band frames in 300 sec exposure each. The fading nature of the source is seen and U ~ 17 mag was measured around 7.5 hours after the burst. The contamination due to the nearby bright stars makes the photometry complicated. Multiband observations and detailed observations are underway. This message may be cited.
