                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
Az Velo Scales:
   At checkout 587.5, 585.8; 586.6 (was 584, no change)
   At 02:00    583.6, 581.4; 582.5 (no change)
Thick clouds kept us closed all first half. Winds and dust also passed
closure limits a few times in the early evening. Clouds began clearing
around 01:00, but radar returns were moving across the top of the county
so we waited until 02:10 to open. Thin cirrus hung around most of second
half, and dust levels increased again.
Local networking issues were resolved before 12 degree twilight.
Both tertiary moves tonight were smooth.
