Bouldin Alfalfa

Robert and I arrived at 14:00 PST. It was a mostly clear, sunny day but cold and breezy. There were sheep on the field to our east. There were some puddles on the dirt road but our field was plenty firm to drive on.

I downloaded met, camera, and USB GHG data. I downloaded and cleared the FD chamber. Robert cleaned flux and rad sensors. I donâ€™t remember the reservoir level, but I think we refilled it at least halfway.

We put two new Arables (sn C006282 and sn C006322) up on the PL post toward the north and plugged them into the solar panels that were already there. We tried to align the Arables so that the tip of the â€œAâ€ icon was pointing north. We pressed the white button for 3-4 seconds to boot them up. The flashing lights on top did their thing.

LI-7500 readings:
CO2 414ppm
H2O 339ppm
T 15.0C
P 102kPa
SS 99--> 99 after cleaning
LI7700 readings:
CH4 1.92 ppm
RSSI 11-->73 after cleaning

We left around 14:35 PST.

Looking at the data in the lab, AirT from the HMP started drifting low in mid Jan.
