Twitchell
7/31/2009

Arrived about 10am with Jaclyn. Clear sunny breezy. Jaclyn will do some ACI curves. I will install new enclosure for LGR.

System was down when we arrived. The GFI outlet at the generator had popped. I left the power down while I rewired the outlet at the tower inside the new box.

LGR, pump, AC to DC converter and air conditioning installed in new box. Another length of tubing added to LGR with external 2um filter. Web cam mounted on outside - need reposition.

Talked to Jim and Bruce. Rice should be fully flowered by end of August. Harvest at end of September. Field will be draining for the month before harvest.

Generator is service the 1st and 16th of every month regardless of the day of week. That means it will go offline on Saturday the 1st.

Matteo swapped LI7500s. See his notes on Sherman.
