                ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
Ominous local clouds delayed opening at sunset. Skies cleared and we
opened around 21:30. Seeing was poor for a few hours, then leveled off to
moderate until around 1am when it improved to sub-arc conditions. Smooth
sailing. Very productive.
