Summary: Water off fields next week, fixed minor problems.

I arrived about 12 noon with Jaclyn and Sara. It was cool and a little foggy. We met Bruce and the building. He said that the will start pulling water off the fields next week. He also said that the yield was about 4 tons per acre.

At the tower the LGR was reading:
12:15PST, 29.19C, 97.15Torr, 13.073usec, 10Hz, 2.052ppm

In slow flow the pressure was 126.06. I adjusted the bypass valve so that the pressure to 142.85Torr.

The solar system was reading 13.2V, 2.9A supply, 2.1A load.

I added a rail for the autocam to slide up and down, but it doesn’t slide so well. Probably need to think a new solution.

The CR1000 data files were recording to the C: drive and filled up that drive. I shutdown Loggernet and moved the files off the C drive. Then restarted Loggernet and reset the file locations to the D drive.

We tipped the spare solar panel base over hoping encourage the critters calling it home to relocate.
