Unfortunately, there were a couple of wisps of smoke when I tested the voltage in the mote and afterword the mote was not sampling properly (based on lights).
This is mote ID16. Looking at the raw data I see that the data stopped at 19:00:43 UTC (13:00 local), resumed for 2 minutes at 19:11 and then quit.
Left site at 13:25.
Later at 15:10 to 15:35 Chris and Tom raised the radiation dark horse to 2.02 meters. Radiation data should be discarded during this period.
