Summary
- Jul. 22th: A problem in the Flywheel PLC prevented to park out the telescope (lost connection with PLC). Because of this trouble, we could not operate the telescope this day. Jul. 23th: By Koji's instruction from remote, we unplugged the power cable of the PLC and replugged. Then, the PLC is back online. For more detail, see ENERGY#32
- Jul. 23th - 25th: Two Schneider engineers worked on a cooling unit for IT container and they fixed it. Now 2 out of 3 units are available
- Jul. 24th: Dragados put gravel in the south east side of the telescope area
- Jul. 26th: GUI stacked due to a wrong shutdown procedure (a human error, access tower&CSS statuses were not properly checked before entering the telescope area) For more detail, see DRIVE#269
- Jul. 27th: Visit of AMANAR from Morocco (14 kids + 16 adults), fully satisfied
- Pointing:
- New Az offset value was derived by Satoshi
- Strange PSF spot shift when the tel. passes Az of 0 deg. Ongoing discussion between Drive and Optics experts
- AMCs: Sometimes PC4 needed to reboot
- Camera (CaCo, EvB):
- Module blocked at high rate (>15 kHz) fixed
- SIS became operable again
- Protection to prevent movement of SIS was implemented (Zd <90 deg)

- Stable version of CaCo by Friday with minor modifications
- New EvB v3 was installed and working well at high rate (>15 kHz)
- GPS was not receiving -> Reboot -> Work fine (receiver and DHCP working)
- We took rate scans, pedestal and flatfield runs
