Wu Command file: 02.10.18.18:15:32.cmd.log Activity: --------- 1) Observation of Southern Coronal Hole Sequence: 02.06_hole1.tcl SCI_SPEC: Characterization of a low-latitude coronal hole. Goal is to measure the properties of a low-latitude 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=100 degrees.
