Uzzo: Commander, Planner R. Wu Command file: 09.10.18.11:09:34.cmd.log Activity: --------- 1) Coronal Hole Intensity Study Sequence: 09.10_HoleIntOVI.tcl, n = 8, m = 0, p = 0, r = 0, e = 0 SCI_SPEC: The purpose of this series of observations is to track the changes in polar coronal hole intensities that are occuring during the current prolonged solar minimum, and compare them to the intensities observed at the time of the previous minimum.
