EPH temp 90.56 deg F NOTES/ISSUES/PROBLEMS From the 9am status meeting: Eleven supports over the weekend, including the extra supports for the penumbral eclipse. Four SCS segments were uplinked, on-board loads are good through 204:17:21. During the DSS-46 pass on Saturday, 119:1150 to 1340, there were dropouts and a high CRC error count. However, the two streams were merged and gave clean telemetry without requiring a re-dump. The penumbral eclipse operations Sunday were completely successful. Much credit and thanks to Rino and Christine for preparing and testing the products and the three CAP's which were run. Time for recovery from normal sun mode was longer than expected, and was tight in terms of when the on-board loads picked up, but was completed successfully. There will be a fire drill this week. Please walk down the stairs past the conference room, or near the printer/water cooler in the DS ops area, and go across the railroad tracks.
