 Observing Specialist: B.Ketzeback
 First half went very well with good seeing at the begining of the
 night and somewhat variable seeing as the night progressed. Second half
 experienced increasing cloud cover from 0130 until we were forced to
 close for a short while around 0315. Seeing continued to be good but
 variable.
