First half:
observer3 died this morning, but the heroic CTIO staff got SISPI up and running on observer2 in time for afternoon calibrations! observer2 was slower than usual as a result, and we learned not to bother running "bigload", but these were minor inconveniences.
Second half:
We started the second half with a problem with the filter wheel not changing filters. It was quickly resolved, only losing us about 0.3 hours around 0450 UTC. We lost 0.35 hours around 0636 UTC when the copilot randomly crashed. This error looked suspiciously like the error that occured 2 nights ago. It was hypothesized to be a network issue but now seems to be a problem with the system, according to Roberto. Before the crash, the queue would randomly stop and we had to manually start it again. We aren't sure if this issue was related, but once decbot was restarted we had no more issues for the rest of the night.

First half:
We also had very poor seeing for about 30 minutes that caused us to lose guiding; we read out that exposure quickly but it is not useful, and then we waiting about 20 minutes until the seeing improved enough to confidently guide again.
Second half:
A fairly smooth rest of the night after the two hiccups described above at the beginning of the second half. Seeing gradually got better as the night progressed. Low wind and humidity, completely clear. A pretty good second half overall. Thanks to Alfredo for his help at the start of the second half!
