              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Nicfps was disconnected when I arrived.  Nicfps needed a cold reboot.  Working now.  Evening started out mostly clear with high thin clouds.
At 01:17 tcc stopped responding to commands. I logged into talk2boxes and reset all 3 axis controllers. Initially pointing seemed off, but after a few long slews the magnesensores corrected the position and pointing appeared to be back to normal.
We were open all night.
