              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shelden R.McMillan
Compressed air dewpoint sensor went off repeatedly.  We called Bill and then Ben, who suggested pulling the fuse if it went off again.  We did.
Otherwise, night was clear and uneventful with good seeing.
