Looked around TMSY (visual inspection) and touched it. Then we did not find any particular issues for TMSY structure so far. No apparent cracks found on the wide blades. No apparent dusts found around the earthquake stops, which would indicate that no severe frictions occured within the suspended table. The table top seemed kept roughly horizontal (Fig. 1). Later with IR, we will be able to check the optics better.

Some note

• The final steering mirror for green reflection on the suspended table seemingly has some stain-like contaminations (Fig. 2); maybe these have been there from the beginning...
• Some metal-like dusts found at the bottom of the table structure (Fig. 3); we just wiped them.
