[Tanaka, Komori]

Today, we successfully maintained the observation state for several hours.
One contributing factor was the relatively quiet ground motion, while another was the implementation of a new OMC initial alignment scheme using the RF sideband, which will be reported later.
Additionally, the glitch rate that excites the pitch, vertical, roll, and violin modes was significantly lower than in recent observation states.

We attempted offset tuning for the following parameters:

• Input alignment to the IFO
• Picomotor adjustment just before the CARM PD
• PR3 alignment
• CARM offset
• Power on the CARM PD
• DARM offset

However, we did not achieve improved sensitivity by modifying these values from their default settings.
We plan to attempt BPC offset tuning tomorrow.
