TITLE: GCN GRB OBSERVATION REPORT NUMBER: 804 SUBJECT: GRB 000926: Optical candidate DATE: 00/09/28 00:41:00 GMT FROM: Johan U. Fynbo at Inst. Phys. and Astro., Aarhus,Denmark T. Dall (NOT and University of Aarhus), J.P.U. Fynbo (ESO), H. Pedersen, B.L. Jensen, J. Hjorth (U. of Copenhagen) and J. Gorosabel (DSRI, Copenhagen) report on behalf of a larger European GRB Collaboration: "Using the ALFOSC on the 2.5m Nordic Optical Telescope, we have obtained U,B,R and I-band imaging of the field of GRB 000926 (Hurley et al., GCN #801) on 2000 September 27.8-28.1 UT. Comparing with DSS-2 (red) we find a bright point source not visible on the DSS-2 exposure. The coordinates of this object are: RA(J2000) : 17 04 09.62 Dec(J2000) : +51 47 11.2 (with an uncertainty of about 2") These coordinates are consistent with those reported independently by Gorosabel et al. This object is detected in both U,B,R and I-band images. A 1hr spectrum covering the region 3500AA-7000AA has been obtained showing a blue spectrum with strong absorption lines. The redshift has not yet been determined. A preliminary magnitude for the object is: R=19.3 +- 0.2. Ingvar Svaerdh and Charlotte Moeller are acknowledged for help with the observations."
