              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
I had to restart the agile heartbeat at checkout.
obs0 timed out and lost connection to the hub at 18:20; I was also logged in on obs1, which did not have any problems. There was no clear reason why this occurred, and it did not happen again.
Otherwise, the night was uneventful, with clear skies and good seeing.
