*Observing Plan*

# Evening standards

# ObsTac

# Community script every hour during first half

# Morning standards

 

*Conditions*

# Non-photometric conditions. Thin clouds came in and out during the first part of the night, and they were getting thicker in the second part. At 4:44am we 

stopped observations because of the clouds. Started again at 5:50am but conditions were still mediocre. Call a night at 6:10am

 

*Accomplishments*

# Survey exposures in z and Y

# Community script ran 6 times

 

*Narrative*

# No standards tonight due to non-photometric conditions

# Seeing varied between 0.8 and 1.5 arcsec

# No SN fields observed tonight
