Sun May 12 10:14:09 2024 INFO: Fill completed in 14min 5secs
outside temp was 28C (82F) at fill time, TCs dropped down to the -120C trip over 14mins before the pressure spike could build. There was a lack of free flowing LN2 which would have resulted in TCmins of -200C.
I have lowered the nominal trip temps down to -130C (full summer mode, as was used last year from June - October).
We will try again at noon today.
