              ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
Partly clear skies first half building until overcast. Closed for about an hour near
23:00 due to humidity spike. Fog in the basin continued to threaten during second
half. Clouding up again around 5am.
Still seeing the bright disk on echelle slitviewer images; probably from a sticky
shutter. Submitted PR #1307.
