Observing Summary:

High humid (75~80%) most of the night.

Observation stopped for ~30min from 21:45 due to the filter wheel problem.

Just after finished observing a target at low alt~38 in NW, 
Filter wheel did not work :  Filter Wheel Is NOT connected  error massage.
The 2.4m observer fixed it by recycling the power of the controller.

After the moon (phase 47) rose at ~23:30, the red-colored airglow was seen in the sky by haze.
Dome closed at ~0:23am.

I was waiting until ~4am. However, there was no chance to observe more targets.
Because the remaining targets were positioned to the wind direction, guiding was difficult.

Around ~4am, the sky was full of thick haze.
I decided to finish this observation at the moment.
