              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
gcam needed an init during checkout. TUI crashed unexpectedly right after sunset, when I was opening the menu to open the TSpec focus script.
The Echelle boresight location was off center, so I adjusted it a few pixels (from 240,249 to 237,250) and made the change permanent.
We were unable to point directly west due to wind for a couple hours, but otherwise the night was clear and uneventful. We closed up around 06:00.
