Observing Specialist: A.Townsend
Lots of rain tonight, along with clouds and humidity which turned into rainy fog at the end of the night; we had no hope of opening.
UW08 time at start of night was originally JH02, traded with Q2 time.
ARCTIC diffuser was rotating when ARCTIC was dismounted this morning, see PR 2251.
Small power flicker at 05:25.
