gcam needed startNubs+init at checkout
At sunset we had about 30% humidity and a temp of 2.5C. The temperature down to about freezing and back up to 4C and 5% humidity around midnight. The Temperature waffled between 1C and 5C for the rest of the night but the humidity stayed low.
There were a few thin clouds during A-half but we had photometric skies after 22:00.
Everything went smoothly!
