Two of the phosphor-bronze bands used for charging the slit batteries on the dome were out of service—one had been previously removed, and the other was snapped.

One of the dome barcode strip started to peel off. Fixed with a double-sided tape.
A potential new oil leak was identified in the mount pillar. An oil puddle was observed in the far-left corner of the left chamber. The suspected source of the leak, an unsealed bolt, is located in the far-right top corner of the same chamber.
