              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Despite thunder and hail in the afternoon, we were able to open the dome a little while before sunset for calibrating the visiting instrument.  Despite rain and hail in the afternoon, smoke from a nearby fired could be smelled.  Fortunately, no glow could be seen.
Skies were mostly clear by mid-evening, but seeing wasn't really good enough for the visiting instrument to work.  It became almost good enough during morning twilight when the wind finally shifted from east to south.  No seeing estimates available.
