Abstract

We present a new high signal-to-noise (S/N) observations of the Diffuse Interstellar Bands (DIBs) in the Local Bubble and its surroundings. We observed 432 sightlines and obtain the equivalent widths of λ\lambda5780 and λ\lambda5797 \AA\ DIBs up to distance of \sim 200 pc. All observations have been carried out by using Intermediate Dispersion Spectrograph (IDS) on 2.5 m Isaac Newton Telescope, during three years, to reach a minimum S/N ratio of \sim 2000. All λ\lambda5780 and λ\lambda5797 absorptions are presented in this paper and the observed values of interstellar parameter; λ\lambda5780, λ\lambda5797, Na I D lines including the uncertainties are tabulated.
