Show moreThe Interferometric BIdimensional Spectrometer (IBIS) is a dual Fabry-Perot instrument installed at the Dunn Solar Telescope that allows two-dimensional spectroscopic observations in a variety of spectral lines. The IBIS/DST will participate in the WHI targeted campaigns on coronal holes (April 3 - 9) and quiet Sun dynamics (April 10 - 16) performing simultaneous high-resolution observations of the dynamics of the photosphere and chromosphere in the coordinated targets. The aim is to obtain insights on the role of the lower atmosphere's dynamics and energetics into the structuring of the coronal plasma and, possibly, into the origin of the solar wind. In this paper we will present the observations obtained as well as first results, and attempt to relate them with recent work performed on quiet Sun chromospheric dynamics. Show less
