TITLE: GCN CIRCULAR NUMBER: 1326 SUBJECT: GRB 020405: Optical afterglow candidate DATE: 02/04/06 01:36:12 GMT FROM: Paul Price at RSAA, ANU at CIT P.A. Price, B.P. Schmidt (RSAA, ANU) and T.S. Axelrod (Arizona) report: We have observed the error box of GRB 020405 with the robotic MSO 50-inch telescope + MACHO imager at 2002 Apr 05.75 UT (approximately 17.5 hours after the GRB). Upon visual inspection of the images, we find a source that is not present on the second Digitised Sky Survey. The source is R ~ 18.5 mag and is located at coordinates: RA: 13:58:03.12 Dec: -31:22:22.2 J2000 with error approximately 0.3 arcsec in each coordinate.
