              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Mostly clear, with cirrus clouds pestering us during A-half. The clouds got worse around midnight, then cleared up later in B-half.
NM06 had issues with their connection tonight, taking over a minute to download each kcam image, so aside from target identification I handled acquisition and guiding. Due to rising humidity, we closed up around 03:30, although the humidity did seem to vary a lot on short timescales so it was hard to judge whether it was real or not. We gave up at 04:30 as the forecast didn't look promising and twilight was approaching.
