I arrived about 9:30PST with Siyan. It was clear, sunny and warm with a little wind. Sitting at the top of the tower I could feel it sway a little in some of the stronger gusts. The grass is still green and the ground looks wet in low areas. The trees still look good.

I swapped the LI820 out of the CO2 profile system and swapped in the LI800. I calibrated the LI800. The ball in the flow meter seemed stuck. I disconnected the up steam stuff from it and the increased flow freed the ball. But when the system cycled through the D solenoid the ball fell to the bottom and got stuck again and the pump labored. I think solenoid D wasn?t opening. I had to take things apart to get D out and then it seemed to start working. I put things back together and removed the flow meter so if D stops working again, at least the flow meter won?t get stuck and ruin the other levels.

I checked the focus on the Stardot camera. I was able to get the middle of the image in focus but the nearest and farthest parts were a little out of focus. I think this can be improved by adjusting the aperture which is wide open right now.

The CO2 profile cal tanks read N2 1200psi, CO2 500psi

The Ethernet cable for the Stardot camera was not seated in the back of the computer tightly and no images had been transferred since I left last time. I fixed this (I think). Then I changed the program on the 23x to not turn on the camera if the 23x voltage was low.

I serviced the z-cam. They all seemed well.

Walked around looking at trees.
