              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Tonight's nightlog brought to you by the letter C!
Clouds.
Clouds kept us closed for the first couple hours of the night.  But we were promised clear skies, dang it!  Clouds continued to roll in but started "thinning" and I opened when I could finally see Venus, which was at 19:56.  We fought with clouds much of the night and a high haze was present even when things looked clear.  NA01 was observing faint targets and, due to the clouds, donated his last 20min to AD02.
AD01 struggled to observe their cold, chunky, carbonaceous chondrites through the clouds.
The ARCTIC diffuser stopped rotating again when I tested it this morning and I updated yesterday's PR.
