              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The sky goes ever on and on,
Down from the dome where it began,
Now far ahead the sky has gone,
And I must follow if I can...
It's only the second night and I can feel the winter upon me. The sky was clear, the seeing was good, the night was long.  Everyone was able to get lots of photons and use all their time.
It's a dangerous business, people, opening up the dome door. You slew up into the sky, and if you don't keep your offsets, there's no knowing where you might be swept off to.   We stared for hours at star rings with our visiting PAO instrument. What can I say about the team except that they were once men; great travelers of men. Then Russet the Assigner gave to them nine sets of hours. Blinded by their greed, they took them without question, one by one falling into darkness. Now they are slaves to our will. We are the Night Gals: Obs Specs, neither living nor dead. At all times we set the center of the Ring, drawn to the power of mag One. We will never stop slewing you.
So bright, so beautiful, aaaaaah preeeciouuuus sky... No problems tonight.
