              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Townsend
We had a few thin clouds during A-half but otherwise good weather and great seeing!
El Paso radar is still down.
ARCTIC checkout images were fine (UL down still as expected) but when the observer started taking biases all four quads read high constant values again (2nd time in 2 nights). Restarted the nubs and did an init to get back to just the UL down (LR down at first too but came back after a few minutes, as normal).
Dataq froze (stripcharts still ok). I had to restart Windows within parallels and power cycle dataq on hub35m to restart it.
No telescope problems.
