              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
I had to power cycle the stripchart mac at sunset, as it was completely frozen.
Agile complained about images coming too early at the start of B half. Logging into nimble and restarting the heartbeat fixed it.
Aside from some occasional wind, dust, and some orographic clouds during A half, the night was pretty uneventful.
