*Observing Plan*

 

# standard bias and dome flat sequence

# evening standard stars

# run ObsTac queue

# Standards carried out

# handover to DD, but used time to do DES starflats

# Observations of Eta Carinae for A. Rest

# end of night calibrations 

 

*Conditions*

 

# weather in afternoon: 4pm (local): Partly Cloudy

# weather after dinner: 7pm (local): thin cirrus towards horizon

# weather summary: 4am (local): some small extinction all night long, humidty steadily rising to 66%

# Afternoon: zeros done 275430-275440 and 275516-275524, (ugriz) dome flats done 275441-275515, checked all ok, but u was lower than expected

# Dome flat tests for G. Bernstein, 275525-275544 No North LED - elog 156461

# Dome flat tests for G. Bernstein, 275545-275564 No West LED - elog 156483

# Dome flat tests for G. Bernstein, 275874-275893 No South LED - elog 156832 

# Winner of post sunset leisure activity: David James as the amazing Wallenda

# Evening: Standards 275587-275604

# Survey Exposures 275635-275723

# SN exposures 275606-275634

# Middle of night: Standards 275724-275738

# Star Flats: 275739-275853

# DD Observations Eta Car 275854-275873

# Back to DES End of night script

 

 

*Problems tagged as Synopsis_Problem*

 

# 23:40 local time had a 4MAP disengagement during the middle of 275630, this needs to be re-inserted into the ObsTac.

 

*Minor Problems and Relevant Information*

 

# Occlusion alarms: 8 alarms during the night.
# Closed side louver at 01:27 local due to wind speeds consistently above 8mph.

 

*Notes for Data Management*

 

# DO NOT process 275630 (guiding lost). Re-insert into ObsTac.
