No mission impact expected at this time, updates will be provided if necessary. Solar activity is likely to be moderate with a slight chance for an X-class flare on days one, two, and three (26 Sep, 27 Sep, 28 Sep). MP: Sep3024A loads should be out for review later on today. ENG: No issues. GOT: No issues.
