              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
A lovely clear night with good seeing throughout.  During first half we tried to observe an occultation event with Agile, which went fairly well and hopefully will put some constraints on the object's size.  On the first slew of second half there was a motion error in altitude which was either caused by moderate wind (22 mph) or by telescope growing pains as a result of springtime.  It was quickly corrected and otherwise observing went smoothly.
