Comments = ASC shows thin cloud later in the night - auroral arcs visible through it, but stars only occasionally. Early in the night there was little aurora, so its hard to tell - the ASC and SDI winds suggest the cloud may have been thicker.  Contamination of SDI winds only appears minor, however.
