G filter failed to go onto camera when taking the last standard. Alberto reset the system and upon attempting to take the exposure interlock DECam (LATCH) was reported as "broken". The following alarms were then raised:
-OCS at 5:56: Interlock DECAM (SISPI) is now broken
-OCS at 5:56: Interlock SISPI (OCS) is now broken
-OCS at 5:56: Component(s) not ready for exposure: FILTER
-FILTER at 5:56: Status is Alarm. Filter will not move. Filter_status: PrevFailed, ADStatus: READY, Previous filter movement failed. Use reset_filter.
Alberto is continuing to work on finding a solution, but since were already at the end of the night we are calling it quits.

*Observing Plan*
# standard bias and dome flat sequence
# evening standard stars
# run ObsTac queue
# middle/end of the night standard star
# end of night calibrations
*Conditions*
# weather in afternoon: 4pm (local): slighty wispy clouds low on the horizon
# weather after dinner: 7:30pm (local): clouds continue to build up low in the sky, high in the sky still clear
# weather after sunset: 9pm (local): thin cloud and half moon directory overhead
# weather summary: 5:30am (local): this cloud continued throughout the night, did not seem to contribute much to the image quality.
# Seeing conditions: Median: 0.84 RMS: 0.15
*Accomplishments*
# Afternoon: zeros done, (ugriz) dome flats done, checked, OK
# Green flash report: remove in the inevitable event that one is not seen
# Winner of post sunset leisure activity: quite a beautiful sunset tonight
# Evening: Standards (SDSSJ0200-0000,WD0308-565_CCD_52json,SDSSJ2300-0000)
# Survey Exposures 591025-591277
# SN exposures: None
# End of night: Standards (SDSSJ1048-0000,C26202_CCD_35,MaxVis)
*Problems tagged as Synopsis_Problem*
*Minor Problems and Relevant Information*
*Notes for Data Management*
# Due to no solution when running qcInv, it might be worth declaring exposures 591097-591098 as bad
