Jelínek\nand A. de Ugarte Postigo (IAA-CSIC),\n\nreport:\n\n\"We have observed the optical afterglow of GRB 060604 (Page et al.\nGCN Circ. 5212) with the 2.5m Nordic Optical telescope (+ALFOSC) \nat Observatorio del Roque de los Muchachos (La Palma). Observations \nconsisted of a 150 s V-band exposure with showed a faint object at \nthe location of the proposed Swift/UVOT candidate, in agreement with\nTanvir et al. (GCN Circ. 5216), plus a 1200 s exposure spectrum \ncovering the range 3200-9100 A with the grism#4. Based on the presence \nof a strong continuum break around 4475 A which we identify as due to \nLy-alpha, we estimate a redshift of z = 2.68. Further analysis is in \nprogress\"\n\nThis message is citeable.",
