Problems: 

The instrument and the telescope behave smoothly.

Comments: 

The night started with clear conditions but it deteriorated considerably during the second half. The seeing never dropped below 1.2, reachng indecent values of 2.5 and higher. Wind was also an issue at some point, with gusts of 30 km/s. This strongly affected the quality of the data, as most of the targets are faint sources (K>13). Clouds continuously rolled in after 3 am.
