                ------------- ACTIVITY LOG --------------
Observing Specialists: G.Saurage
AzVelScales: 576.1, 578.9 avg 577.5
Mostly clear night, moderate winds, variable seeing. TUI crashed once, PR
684, but recovery was fast. No time lost. Second half the NA2 guider froze
once (was not updating, still said guiding). Restarting the nubs brought
it back. No time was lost, but it may have been long enough without guide
corrections to see some drift.
