I arrived about 9:30am with Jaclyn. It was sunny and relatively warm with almost no wind. The field is mostly drained, but still has some shallow puddles.

The LGR was off when we arrived. It had hung up in a reboot attempt. Cycling power fixed it. I tried another keyboard/trackpad and it still did not work. The internal connectors seem okay.

On restart the LGR reported:
9:50PST, 15.18C, 99.72Torr, 17.193usec, 10Hz, 2.258ppm

I adjusted the bypass valve to raise the pressure to 148.72Torr.

The computer had been sleeping for four days – probably when power went down.

I collected data and swapped the CR1000 card.

Jaclyn cleaned the radiation sensors and collected the plant cam images.

The solar system reported 14.5V, 3.3 A solar and 0.5 A load.

We left for Sherman about 10:15.
