Problems: 

Minor issue with interlock broken. Exposure 651308 was lost. Message said "component not ready (DONUT)". We hit "configure" and got back to normal. 

At the second part of the night images seems to be elongated.  We didnt find anything wrong with the telescope (for example, doing 90s exposures didnt change anything).
