Kathy Vivas observing for Lin; Guillermo Damke observing for Dey+Schlegel

First part of the night: smooth operations. Mediocre seeing.

Second opart of the night: smooth operations until 1:45 local time, then closed due to clouds. Decided to quit for the rest of the night around 4:30am local time as the clouds got worse and the forecast was very poor...
