              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Bring on the cooomeeeets!
I guess we sang the song off key because we ended up bringing on the clouds.  Clouds, clouds, clouds, all night.  The virga was too close shortly after sunset and we closed for about half an hour.
Seeing was moderate but it was a fight to get the photons to fall. AD02 had some luck with their observations but poor UW09 was observing faint stars and threw in the towel around 4:00am. We were all rather sad and dejected the whole night almost like we were...under the weather.
The NA2 guider had an interesting problem tonight where it would not focus and gave the error:
relPiston ... failed: Aborted; Actor='gmech'; Cmd='relPiston 1000.0'
We tried a gmech remap along with a hub restart but neither helped.
It was working fine at the beginning of the night.  I sent a PR.
====================
Hal-y, Hal-y, quite contrary,
Howell do your comets go?
With silver tails and cloudy shells,
…and all our heads hung in a row. :(
