I arrived about 11:30PDT with Sara. It was clear, sunny and hot with a strong breeze from the north west. The field has been plowed and was actively being disked while we were there. They are planting some of the other fields.

Everything was running okay. The 7700 needed a bunch of water and its RSSI was 17. After cleaning the mirrors it was 79. The solar panels are dusty too. All the tractor work must be kicking up more dust than usual.

We swapped out the old Li-7500 and the old 7550 and old sonic for a new 7500A, 7550 and sonic with analog outs. The new system seemed to be working. I had to tell the 7550 to connect to the 7700 head, but it seemed all the proper channels were being recorded. I set the 7550 box time to PST and its automatic time sync was off. I also set the LI7700 time to PST and its time sync was set to automatic.

We removed the CR1000.

We collected data from the cr23x and the cameras.
