| DCRCs powered overnight. Pumping on IVC with turbo pump overnight. | |

| Tower/MC/Coldplate = 39/34/159 mK, Still = 102 mK / 550 μbar, G1/G2 = 168/152 mbar, 1K Pot = 1.453 K / 2.2 mbar, MB = 72.1%. Tweak 1K Pot. Boiloff rate: nice and slow. 5 min and 30 min pressure releases yesterday worked well |
