              ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
Clear skies. Good seeing.
At UT 03:27 Echelle Slitviewer became unresponsive to commands reporting a ecam f
text="text=\"sendCmd timed out: timed out\"" error in TUI. Restarting nubs did
nothing. It seemed ecamera was not connected. I could not log into Slitty remotely
and the peripherals on the computer itself are not much help either (see PR#1110).
Therefore had to power-cycle. Everything came back up properly, but still cannot
communicate with Slitty.
Happened again:
UT 11:19:00 UW15.GEORGEW.ecam 8740 ecamera f text="sendCmd timed out: timed out"
UT 11:19:00 UW15.GEORGEW 92 ecam f text="text=\"sendCmd timed out: timed out\""
Had to power-cycle again.
In between programs I took a few defocused ecam images with the hope these might
reveal the state of collimation after the change in the PMSS T sector during the
day. Nothing is obviously wrong to me. Please see images in ecam/UT100325/e1115
through 1119.fits.
