SHIFT SUMMARY:
H1's been locked 53.5hrs (1hr from our O4 longest lock *knock on wood*).
Main news of today was the H1 Chiller Pump#1 going down. Tyler as well as a contractor spent most of the last 6hrs dealing with this and we are currently set and running with Chiller Pump #2.
There was 2hrs of commissioning by Gabriele & Elenna as well.
We appear to have a ~5Mpc increase in range....waiting to hear if this is due to the commissioning or working with different chiller pump!
