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 $lambda$5780 and $lambda$5797 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 $lambda$5780 and $lambda$5797 absorptions are presented in this paper and the observed values of interstellar parameter; $lambda$5780, $lambda$5797, Na I D lines including the uncertainties are tabulated.
