| 0000 | Tower = 70.9 mK |
| 1310 | Fill LN2 cold trap bath. Main Dewar went empty before fill finished. Cold trap bath is about 2/3 full. |
| 1310 | Tower/MC/Coldplate = 67.9/31.8/200 mK, Still = 1.30 K / 0.095 mbar, G1/G2 = 145/143 mbar, 1K Pot = 1.66 K / 30 mbar. MB = 22.0% |
| Tower temperature is decreasing linearly, very slowly. | |
| 1328 | Start LHe transfer at MB = 20.5% |
| 1410 | Finish LHe transfer at MB = 93.1% |
| 1425 | Above is before we took out the transfer stick. MB = 91.3% |
