The star was discovered with UT2/UVES in Period 70. Its stellar parameters are [Fe/H]=-3.09, Teff=4800K, logg=1.7. A preliminary abundance analysis, based on the UVES "snapshot" spectra, yields [Eu/Fe]=1.29, [Ba/Eu]=-0.56 and [C/Fe]=-0.27, making this star an excellent target for studying the nature of the r-process as well as for an attempt to detect uranium. Hence we now want to obtain spectra of high resolution (R=60,000) and good S/N (~70 per pixel) of this star, in order to carry out a precision abundance analysis and an attempt to detect the U II 3859.57 A line (or otherwise derive an upper limit for the uranium abundance). We have chosen two settings, DIC1/346+580 and DIC2/437+860, to reach full wavelength coverage. Both settings cover the U II line, so that the S/N at that wavelength will not decrease due to using two settings instead of one. 1x1 pixel binning is used to ensure proper sampling. We do not use an image slicer because the object is relatively faint (V=15.92; B-V=0.77) and hence sky background subtraction is critical. Furthermore, in Service Mode the dichroic settings can not be used together with an image slicer. To facilitate cosmic ray removal, and to allow for flexible scheduling, the total exposure time is split into 31 exposures of at most 1h each. There are 16 Observing Blocks for the DIC1 setting, and 15 for the DIC2 setting.
