Moon phase: 

Summary: We were hopeful at the start, but had some intermittent closes
from clouds. After the second closure, we remained closed due to
humidity being above 90 percent. The humidity pinned at 100 percent for
four hours, prompting us to call it an early night. No calibrations were
taken for LBC, but we can use the archival ones from last week.

Details (All times UT):
----------------------------------

Plan: Begin at twilight with the KELT 16 observation, which we will
nominally observe till 09:45, taking up most of the night. Post that we
will switch to LBC, and stick to that for the remainder of the night.

Updated plan: Spotty clouds as sunset approaches, making odds of
successful KELT-16 observations low. Planning to run LBC observations
instead, working way down priority list.

01:24  - sunset

02:05 - opening the enclosure. Still some clouds nearby so there is the
        possibility that we might need to close in a hurry. Sticking to
        OSUmonitor as interruptable program.

02:11 - pointing check

02:23 - collimation and focus done, starting copointing. Not actually in
        focus, re-focusing.

02:52 - Closing dome due to approaching clouds while
        focusing/collimation still in progress.

03:09 - Re-opening.

03:38 - Focused and mirrors aligned, beginning first science observation
        (for OSU_monitor N6503).

04:00 - Finished N6503, moved to N6946. 

04:08 - Started N6946 for OSU_moniter

04:09 - Closing due to cloud.

05:21 - Clouds looking better, but humidity now above 90% limit for opening.

07:41 - remained closed due to 100 percent humidity for past two hours

09:05 - still closed due to humidity

10:40 - Calling it early again, humidity pinned at 100 for the past four
        hours.
