Thu CP1 Fill, issues with Thermocouple-B

Thu Dec 19 10:15:29 2024 INFO: Fill completed in 15min 25secs

Gerardo confirmed a good fill curbside.

TC-B suddenly jumped up in temperature at 04:16 this morning by +15C. Gerardo took a look, both TCs are currently encased in ice (see photo).

TC-mins for today's fill (trip temp = -65C) TC-A = -116C, TC-B = -56C. Which means only TC-A was able to stop the fill by exceeding the trip temp.
