                ------------- ACTIVITY LOG --------------
 Observing Specialist, 1st Shift: Noel Camron Hastings
     The telescope was not opened during the first half of the evening
due to heavy cloud cover.
 Observing Specialist, 2nd Shift: Russet McMillan
 Near the latter part of the morning, the clouds began to thin, and an
 edge was visible that looked as if it would reach us just at dawn.
 We opened at 04:25 and were able to focus and observe a standard
 despite the clouds and very poor seeing, but the science targets,
 especially those at high airmass, proved more difficult.
 The sky cleared at about 06:00.
