GCN Circular 5237
Cedric Ledoux (ESO), Paul Vreeswijk (U. of Chile/ESO), Alain Smette (ESO), Andreas Jaunsen (U. of Oslo), and Andreas Kaufer (ESO) report on behalf of a larger collaboration: "We triggered Rapid-Response Mode VLT observations with the Ultraviolet and Visual Echelle Spectrograph (UVES) following the Swift detection of GRB 060607 (Ziaeepour et al., GCN 5233). A series of exposures were started at 5:19:52 UT, i.e. 7.5 minutes after the Swift/BAT trigger. The spectra cover the approximate wavelength range 330-670nm at a resolving power of about 7 km/s. A preliminary analysis shows the Lya forest up to a rather weak Lya line, as well as a CIV doublet at a redshift of z=3.082, the presumed GRB redshift. We also detect two probable intervening Damped Lya systems (DLAs) at z=3.050 and z=2.937. It's a pleasure to thank the excellent support of the Paranal staff."
