                ------------- ACTIVITY LOG --------------
 Observing Specialist: B.Ketzeback
 Az Vel Scales: 588.2, 591.5 avg 589.9. Was 580.0 changed to 590.0
 During checkout and then again during evening twilight the ICC for
 Agile (Nimble) crashed or froze up and required a power reset. No
 science time was lost.
 The first few hours of the night had some of the best seeing I have
 seen in the optical since I have been here hovering between 0.5 and
 0.8 arcseconds for several hours. Later during the first half seeing
 degraded some but still was quite nice. Second half the seeing
 became quite poor and then settled down again around 3am. Clear skies
 all night.
 No other problems.
