TITLE: GCN GRB OBSERVATION REPORT NUMBER: 2006 SUBJECT: GRB 030323: Gemini South VRI obsevations. DATE: 03/03/29 23:26:48 GMT FROM: Jose Maria Castro Ceron at STSciInst <josemari@alumni.nd.edu> José María Castro Cerón (STScI), Javier Gorosabel (IAA-CSIC/STScI), Andrew S. Fruchter (STScI), Andrew J. Levan (U. Leicester) and James E. Rhoads (STScI), on behalf of a larger collaboration, report: "We have performed VRI band observartions of the optical afterglow (GCN 1949) of the GRB 030323 (H2460; GCN 1956). For each band 30 x 45 s images were obtained with the Gemini South 8.1 m Telescope (+Acquisition Camera), as follows: BAND | UT MAR 2003 | MAG | ERROR(*) ------------------------------------------- V | 27.135--27.161 | 23.04 | +/-0.03 R | 27.166--27.186 | 22.27 | +/-0.04 I | 27.186--27.205 | 21.78 | +/-0.05 ------------------------------------------- * Only statistical error. The photometric calibration is based on the star located at RA(J2000) = 11h 06m 08.82s, DEC(J2000) = -21º 46' 37.5", which has been fixed at V = 18.97, R = 18.28 and I = 17.71 (GCN 1948). The coadded R band image can be found at: http://www.stsci.edu/~josemari/GRB/GRB030323/grb030323.gemini.R.gif This message may be cited."
