              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had several DD projects tonight and *all* the instrument changes! Wasn’t was poor all night but each science project was able to get time.  Clouds stayed around all night but finally started coming in so thick during engineering time that not much was accomplished.  We were able to adjust the focus on DIS but then weren’t able to observe any stars to see how best dis focus compared with dcam.  We switched to arctic around 3am to try and instrument block but the clouds never let us see a star and we gave up at 5am.
The left dome door is making more of a creaking/grinding sounds now, different from the clunks I heard a couple months ago.
