With Uchiyama, Yokozawa, Yuzu, Takase
We found a pool of liquid the bottom of the EXA like a lake.
The size of the lake was difficult to estimate, but the order is about 1cm in depth and 20cm in diameter.
- Liquid-like material was seen on the optical table surface, on the Pcal mirrors, and on the H steel.
- Also there are small drips in the vacuum tube between EYA and EYC.
- We used a black light to check them, and they looked slightly blue or green.
- We used a long band and a Kimwipe to get a little of the liquid. To the touch, it was viscous and oily.
- There was no liquid on the NAB, but there were traces of what appeared to have dried up.
