SHIFT SUMMARY:

Not much else happened today after the end of Ryan S's shift. Sheila and Keita went out to ISCT1 to align the POP path but were not able to make much progress, so commissioning stopped for the day.

JAC is being left LOCKED but IMC was taken OFFLINE so Jim can take some measurements.

LVEA is LASER HAZARD
