                ------------- ACTIVITY LOG --------------
 Observing Specialist: G.Saurage
AzVeloScale: 578.9, 578.2; 579.1 (no change)
Clear skies. Lots of instrument switching but no problems. TSPEC test darks were
taken before and after each time it was moved, no zero file issue. Used autofocus
script on NA2 guider most of second half; worked nicely.
