GCN Circular 2590
Brijesh Kumar*, Arti Goyal*, Ram Sagar* and D. Bhattacharya** (* Aryabhatta Research Institute of Observational Sciences, Nainital) (** Raman Research Institute, Bangalore) report: Optical observation of the field of GRB 040511 (HETE trigger #3218, GCN 2588) was carried out using a 1k x 1k CCD Camera covering a field of 6'x 6', mounted on the 104-cm Sampurnanand telescope located at Aryabhatta Research Institute of Observational Sciences, Manora Peak, Nainital. We took frames at 20:17 UT on 11 May, 2004 (7.16 hours after the burst) at large (about 5.4) airmass. We obtained three 300s R band images. Visual comparison of the combined images with the USNO-A2.0 catalog does not reveal any new source down to a limiting magnitude of R ~ 19.5 inside the 2.67 arcmin error circle around the position reported by HETE SXC (GCN 2588).
