1820 - Started setting up the dome

1855 - Started taking calibrations

1940 - Completed calibration

1943 - Waiting for the sun to set

1951 - Mirror doors are not opening

1951 - All 4 mirror doors opened while doing flats and closed properly and while opening it after the calibrations, all four of it is not opening

1956 - While looking at the telescope, we found the motors of the mirror doors to be running even after failing to open the mirror doors

1957 - pinged Ian and vincent on discord and waiting for reply

2015 - Stopped the motor of the mirror doors using a tissue as the motor was getting hot

2016 - Insulating connection between conductors

2016 - Or if it is a distance actuated switch maintaining the distance with that tissue

2019 - For the note we are not physically forcing the motor to stop

2022 - We are assuming that the set screws came loose and the pullet slipped off

2226 - We fixed the pullet by placing the belt back at it

2231 - The belt on the pullet at south side of the mirror doors came out while trying to open and we fixed that as well

2233 - Now everything is looking good but when we click open from the control computer, the mirror doors are not opening

2236 - The motors on the North and South are running but the motor on the east side of the mirror doors feels getting hot

2242 - While trying to close the mirror doors from the control computer, only the motor on the North starts to spin. But when we try to open it up, every motor is running but its unable to lift the mirror doors up for some reason.

2251 - We are waiting for like 10 minutes for the motors to cool down a bit and check if its still not running and looks safe and then we'll start closing down

2315 - Started close down procedure
