Problems: 

System issue at the beginning. Zero's were taken but could not see the images. Reset and retook zeros which worked. The issue did not appear again.

At around 6:21 UTC, seeing rose to be around 2.4, which is when we stopped observing, waiting for seeing to go below 1.7. An hour later, seeing went to ~1.6, so observation resumed for 10 minutes before jumping to ~3. Then waited around 45 minutes before seeing went down to 1.45 and then fluctuated from 1.2-1.9 since then.
