See http://cxc.harvard.edu/mta/SOT_reports/sot-shift.html Shift L5647 Start at 006:14:00 GMT PLAN ---- At the 006:1125-1225z comm pass the spacecraft was discovered in Normal-Sun Mode. All systems responded nominally. The initial indication for the cause of NSM is an IU reset (similar to 2010 event): OBC-B is halted and VCDU out-of-sync between the OBC and the CTU. Looking to obtain additional comm for NSM recovery SOP execution. 9 AM Summary --------------------- Notes: 3 Supports Completed (Total time: 6.9 hours) CAPs: 1090 006/1222z OBC VCDU Count Resynchronization to CTU 1085 006/1224z Coarse OBC Error Log Time Tag Test Radiation: Quiet. Solar Activity Forecast: Solar activity is expected to be low with a chance for M-class flares and a slight chance for an X-class flare on days one, two, and three (06 Jan, 07 Jan, 08 Jan). MP: NSUN replan will be worked today, including a possible TOO. Eng: No issues. GOT: No issues.
