                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
High dust until after 2am. Dust values stabilized just a little below
closure limits by 2:30. Opened at 3:00. Very poor seeing >2.5” most of the
time. After 5:30 the clouds thickened such that it was really pointless
for data.
