                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Russet McMillan
 The entire night was clear, with light winds and lovely conditions.
 Seeing was variable with a strong position dependence; the
 measurements shown in the focus log were all obtained in the
 northwest, where seeing tended to be good, but in the east the seeing
 was up to 1.6 arcseconds much of the time.  We did obtain several
 hours of good seeing just under an arcsecond in the right parts of
 the sky.
