Problems: 

None, besides from yet another night of impenetrably bad weather. There seemed to be a brief SISPI crash at the beginning of the night, but a restart (and some help from the La Serena crew) fixed the problem.

Comments: 

None, aside from the fact that the humidity never dropped below 90%, and was at 95% for almost the entire night.
