                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
AzVeloScale: 575.4, 574.0; 574.7 (change to 576)
AltVeloScale: (no change)
Overcast skies and local radar activity for most of the first half. Sky began
clearing around 23:20, and we opened at 23:50. Mostly clear skies second half.
Apollo observers note tracking was very stable tonight, perhaps better than usual.
Seeing was poor around midnight with moderate dust levels. Seeing improved some as
second half progressed.
