Comments (times in UT):
00:00 - Needed to correct the focus on the telescope, decided to retake standard afterwards.
00:54 - Switching to SOFI. Using historic focus details as the quality of the image analysis was poor. A few technical issues with SOFI that we are continuing to monitor.
03:35 - Switching back to EFOSC.
