We had bad weather at the beginning of the night. During the second half of the night we had problems with the guider. It would suddenly stop guiding. After pausing and resuming the exposure it would restart again. Toward the end of the night though, it just stopped working completely.
We got the following alarms when the guider stopped: "GUIDER GUIDER continnous null" and "GUIDER GUIDER no active CCDs".

Seeing got progressively worse during the night. Also, the ellipticity values got higher and close to 0.2 during the second half of the night. In some frames it looked like the telescope had jumped judging by the appearance of the stars.
