Goal is to measure the properties of a non-polar coronal hole. In particular we are interested in the coronal conditions (intensities and line widths for HI Ly-alpha and OVI 1032/1037) as a function of height and latitude. We will compare these properties with the ones found in polar coronal holes. Roll positions are VL-corrected for PA=294 degrees.
