Problems: 

1. Some guider difficulty on a few occasions during the night (about 4 times during the night for duration of ten minutes or so). 
Changed isolartion range and exposure time of guider, still failed to find all guide stars during a handful of images. 
These are quite crowded fields...

2. Lost about half an hour::

Error messages:
23:07 problem moving fragment image
23:07: Error transferring image 322725 to comfort display
Comfort display did not display nearly all of the top-left quadrant of the image, however the image displayed on Observer2 with kentools looked fine (all chips present).

Stopped queue. Then restarted queue (hitting "go") to no result (not even error message).  

Image 2731 lost

Steps taken:
Tried to recover comfort display without success, had to restart SISPI
Back on sky 23:35
