Mid Shift Status
- LVEA's GV7 for the X-arm opened just after 8am.
- Green beam from EX seen at LVEA's ITMx shortly afterward. Need to align all optics upstream to allow IR light to shine back to EX.
- PSL Shutter opened for IR light.
- ETMx Seismic Table tripped. This was later determined to be due to manlift moving outside of the building and drilling (Ken electronics work); this work was stopped.
- The Seismic DMT viewer was down for first few hours (Dave & Jonathan worked on getting it back).
- Alignment work continues during the lunch hour....
