Lockloss 16:11:09 UTC
No obvious cause, the big pick up truck is moving tumbleweeds not far from the OSB so that could have had an impact. FSS stayed locked.
Tyler, Chris, Scott and Roger are using the opportunity to clear the tumbleweeds blocking the office windows! Photo here
(We had one lockloss from Move spots which maybe could have bee due to the pickup moving on the gravel, but we also had a lockloss here last night.)

It was my understanding that this activity with the tumbleweeds took place AFTER the lock loss. We typically try to use the machine only in areas where it will not disrupt the instrument or if there is a lock loss. We do not want to be the cause of the instrument going down.

Yes Bubba, the running of big green was after the lockloss, once we decided it shouldn't hinder relocking.
However, I think that the 1-tonne truck was driving on the gravel in front of the OSB before the lockloss and I wanted to record this for later analysis as it could have been a factor in the lockloss.
