              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Multiple problems tonight.
During OU03 we had an error with an axes but it was unclear which one.  While the observer was making offsets the telescope refused to slew giving the error: "Slew failed: Sub-command(s) failed: DRIFT: Timed out"
After multiple attempts of axes inits with and without a stop button, logging in to talk2boxes shows that all axes were responding properly.  After closing out of talk2boxes, disengaging a stop button, and initializing the axes, we had no further problems.
A ToO was engaged tonight by UW02 and took over the UW09 program.  However, they didn't need the full time and we began engineering time after 03:14 am.
We conducted an instrument block for ARCTIC during EN01.  There was an issue mounting ARCTIC which was later found to be a power cable to the shutter becoming wedged between the instrument and rotator.  The power cable was wrapped around the ARCTIC cart and had to be unplugged, causing shutter errors.  Once the shutter was restarted we were able to continue with the instrument block.
Too tired for poems tonight, but, if you’ve never heard of the video game “Portal” you should check it out, there might be a reference tomorrow…
