Gorosabel (LAEFF-INTA, Madrid, and University of Amsterdam)\n\nreport:\n\n\nThe error box of the burst GRB 000301c reported by Smith et al. (GCN\n#568) was imaged with the Calar Alto 3.5-m telescope on March 3, 4:41 UT \n- 5:38 UT using the near-infrared camera Omega Cass. The frames\nwere taken in the course of a project whose goal is to measure the\ndegree of linear polarization of GRB afterglows. The limiting\nmagnitude of the K'-band image is about K'=19 after adding all images\ntaken at different position angles of the wire-grid polarizer. \n\nThe potential optical transient reported by Fynbo et al. (GCN #570) is \nclearly detected. Based on the assumption that the B-R colour index of\nthe star USNO 125_07686794 is representative for its spectral type, a\npreliminary estimate of the K'-band magnitude of the potential afterglow\nof 17.4 was derived.\n\nThe image is posted on the Tautenburg Web page at\nhttp://www.tls-tautenburg.de/research/grb000301c.html.\n\n\nThis message is quotable.",
