*Observing Plan*

# Community observer first half: Director's discretionary
# Mid-night standards
# Turn on ObsTac
# Morning standards (while watching SISPI closely!)

*Conditions*

# Overcast, with rain in the vicinity. Dome remained closed for entire night. 

*Accomplishments*

# successful PTC sequence (exposure 467111-477296)

*Narrative*

# Dome closed 1st half of night
# When conditions seemed to be statically bad, we decided to run a PTC sequence.
# 2 failed attempts: forgot to change proposal id and decided to add a flush_vsub, since it was unclear if this had been done, given the 1st half cancellation.
# 3rd attempt failed due to SISPI hang (see eLog) that required restart of SISPI instance.
# Finally successful from exposure 46711 onward.
# Dome remained closed for remainder of night.
