Previous Day

overnight: fridge looks stable with tower = 40 mK and slowly falling. No temperature excursions. 1K pot has been stable at 1.45 K / 4.0 mbar
1337 Tower at 37 mK and slowly falling. G1/G2 at 229/219 mbar.
1348 Liquid nitrogen filled to full. G1/G2 now at 214/206 mbar and slowly rising. P1 at 0.055 mbar. P2 at 4.5 mbar.
1400 At this time it looks like another temperature excursion started. Temperature rose by 2 mK over 1 hour.
1740 Sharp temperature up-tick, wait to see if increases further; incidentally this seems to correlate with when I first woke up the linux monitors
1743 may have just been a glitch
1802 gave a little extra still heat to see what happens still heater: 1.0 mW → 1.1 mW
1806 gave a little extra still heat to see what happens still heater: 1.1 mW → 2.0 mW; might be very slight decrease in base, not much
1808 now base starting to trend down faster G1/2 238/227, 1K pot 1.46K/ 4.0 mbar
1848 base got to a min of 36 mK, but now is sharply rising. May be another temperature excursion
1855 go back to 1 mW on still heater
