                ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
Nice clear skies all night. Decent seeing.
My TUI began repeated crashing at 02:28 (by “crashing” I mean the windows
all suddenly disappeared). Jeppe’s file system seemed to be full. I didn’t
feel I was qualified to resolve this issue so I worked the rest of the
night from Newton. No time was lost, since science continued all the
while.
