              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
A clear night with moderate seeing.  Everything worked well (no moves of
the DIS turret were needed).  Heavy dust down in the basin did not move
up the mountain so dust levels here didn't go too high; a strong smoky
smell in the dome in the morning was apparently from distant large fires
in western NM or eastern AZ.
