448400:00-00:4500:45During OPS ControlDesk was not moving the tracker. The RX and TX lights were orange. The weather was bad (rainy) and so there was time lostI started the dSPACE several times and I got the Tracker to move.
407706:32-06:3500:03While on trajectory; TCS gui just disappeared from the screen.. no error no pop up... just gone.Found a few defunct tcs gui on jove; killed them and restarted the gui.
447807:05-07:10, 08:21-08:26, 11:15 - 11:1700:12Tracker server and TCS server both died off while on trajectory; according to Niv this was the error him and Jason were waiting on and were expecting.Performed a kill -6 on both servers so software team has a core dump file to study; restarted servers.
448506:00-06:2300:23mirrors out of the array; M73, M48, M76 moved in and stacked. Also M72, M91, M89 were found and stacked but since the sensors were not adjusted SAMS could not keep track of them because of all the -386 errors. Since mirrors were uncovered moved them out of the array by +50 tip and +50 tilt so that they would be out of the field of view. When stacked the actuator values for each were M71 i62270 j62023 k52859 M91 i49917 j50505 k62663 M89 i52408 j71863 k58942
