Comments:
I started the night with the KN candidate as it was very low (as suggested by Morgan)
Sky flats for z-band were repeated in the morning as they were not finished in the evening
Relatively stable seeing through the night.
The last telluric standard and spectroscopic standard with SOFI were taken during morning twilight
