ADC_Keywords: Clusters, globular ; Stars, population II ; Photometry ; Effective temperatures ; Radial velocities Keywords: line: profiles - globular clusters: individual: NGC 2808 - stars: atmospheres - stars: mass loss - stars: Population II - techniques: spectroscopic Abstract: We present the results of the first observations, taken with FLAMES during Science Verification, of red giant branch (RGB) stars in the globular cluster NGC 2808. A total of 137 stars was observed, of which 20 at high resolution (R=47000) with UVES and the others at lower resolution (R=19000-29000) with GIRAFFE in MEDUSA mode, monitoring ∼3mag down from the RGB tip. Spectra were taken of the Hα, Na I D and Ca II H and K lines. File Summary:
