Newsam (Liverpool) report:\n\nWe observed the optical afterglow of GRB 041006 with the 2.0m Liverpool\nTelescope on La Palma. We obtained BVRI imaging commencing 8.2 hours after\nthe burst. We report preliminary R-band estimates:\n\nR = 20.4 +/- 0.1 mag at Oct 6.92 UT  (exposure time = 600s)\nR = 20.6 +/- 0.1 mag at Oct 6.98 UT  (exposure time = 600s)\n \nThese values were derived applying zero points inferred from the Landolt\nstandard stars as cited in Fugazza et al (GCN 2782), which result in\nmeasured magnitudes ~0.3 mag fainter than those given in the USNO\ncatalogue. \n\nstar            RA            Dec           R mag    err\n----------------------------------------------------------\nU0900_00213234  00:54:47.045  +01:14:05.60  17.75 +- 0.04\nU0900_00213423  00:54:50.131  +01:12:10.33  18.90 +- 0.04\n\nIn summary, we confirm the R-band magnitude measured by Fugazza et al\n(GCN 2782) at 7.07UT.",
