Transponder switched from MOT1 to MOT2 and TWTs switched, meaning we should be back on the HGA. USO Temperature rose from about 6C at 04 h to about 11C at end of day; it likely will continue rising into today. There is also a low-amplitude 100 minute oscillation on the temperature curve indicating spacecraft rotation. Total volume of channelized engineering data for the day was almost 116 MB, rather than the 10 MB and less that has been typical for several weeks. L-0200 is still at 4.08 volts; L-0201 is a little lower than before the spacecraft emergency. Open Loop Data ============== Data Collection --------------- No new data Closed Loop Data ================ Data Collection --------------- We have obtained the following files from OSCAR and EPIC. The ATDF and ODFs were obtained earlier, but have only now been labeled and logged in our data base. The EOP files are current acquisitions.
