Yesterday morning (or, rather, the day before yesterday, since I forgot to publish this yesterday) Laura and Natalie were testing the sun sensors using the fake sun. I went exploring outside and found a black widow, which was cool because I had never seen one before. Then in the afternoon Matt and I (mostly Matt) got lots of shots of the still-open cryostat and the half-wave plate rotator modifications.
Matt also learned that since he’s sharing the lab camera (he forgot his, and is very upset about it) that he can take tons of random pictures and I will be the one to sort through them. He started abusing this privilege—but not enough that I didn’t still sort them…he’s good.

Laura and Natalie feel for the point it’s focusing at

I find the process pretty amusing looking, so take several pictures

They eventually have a sort of God-Adam moment

Matt starts taking tons of random people shots, starting with Nick
-
-
And catches lots of people by surprise. Like me

Lorenzo is really surprised
-
-
He catches Laura too
-
-
Elio, not so surprised. He’s hard to surprise
-
-
Natalie needs more coffee before becoming capable of expressing surprise

More gears, from the other side

I had just fixed something. I no longer remember what. It must have been important
