MDM Observatory 1.3m Telescope Observing Report for 2021 May 07

Observer(s): Donghoon Son
Institution(s): SNU

Instrument: Templeton

Worked for 8 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds from 23:30 until .
   Beg: Seeing 1.7 arcsec, Clear, Winds High
   Mid: Seeing 1.9 arcsec, Fog/Low Clouds, Winds Moderate
   End: Seeing 1.8 arcsec, Cirrus, Winds Light & Variable

Observing Summary:

West wind was strong enough (15~10mph and gust~20mph) to shake the telescope from start to ~2:30am.
However, everything went well thanks to the closed dropleaf.

After midnight, thin clouds strolled in.
But, all the planned targets were observed.

Because thick clouds are seen on the sunny side and thin clouds (fog?) exist in all sky, 
I decided not to take the morning flat.
The dome was closed early at ~3:10.
