Echelle images were all zeros at checkout, needed an ICC restart and then it was
fine.  We also had exciting adventures with ARCSAT during first half, which will
require some more effort to get working.  After that, the only challenge was varying
high clouds.
Candace came on shift for B half. And forgot to record the focus on the echelle. It was 1.06". Clouds continued but the wind hasn't hit yet...
