Alistair, first half of night:
Tech downtime: 0.3 hours
Reason: At the poimting cehck, noticed HA and ZD not appearing in the headers, also not updating in the telemetry viewer. OK on the TCS side. As a consequence Kentools “center” would not work. Restarted SISPI but that did not fix it. Then, apparently without doing anything, HA and ZD started appearing in the headers and telemetry display. The images affected were 558305-558403.
Tim, second half of night:
The SISPI telemetry viewer has got systematically slower through the night.
Alberto noticed the LN2 pressure rising. Investigation showed that this started at about 10pm. Further investigation shows decaying vacuum in the 1r line. Time to pump?
