              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
A dust spike at sunset kept us closed for the first portion of the
night.  After that, everything went smoothly.  Seeing was more stable
than previous nights so during changeover I checked and found that there
is still a modest discrepancy between the slitviewer and spectrograph
best focus values; we will work around this until there is time to fix it
properly at the next engineering.
