              ------------- ACTIVITY LOG --------------
Observing Specialist: J.Dembicky
Seeing got worse >3 arc sec during the first half.
My DIS slitviewer image was not updating (other users had been reporting this behaviour as well in the past).  I also noticed that the back/forward buttons were non-responsive, although the currecnt checkbox could be checked/unchecked (didn't affect image).  I simply closed the slitviewer and re-opened it and the image started updating correctly (no exit or restart of TUI required).
Seeing improved during the 3rd program as the winds change direction.
