(* means a trouble report has been issued or appended to)
1st half observing specialist: K. Gloria
2nd half observing specialist: R. McMillan
Clouds and the threat of rain during first half and humidity during
second half cost us most of the night, aside from a period from 23:00
to 23:45 when we were open just long enough to get a little data with
DIS.
