                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 Clear first half with moderate seeing; mixed clouds second half.
 Although it was safe to remain open until twilight, the second half
 observer had faint targets and was able to integrate less than half
 the time through the clouds.
 After several motion errors during afternoon test slews, the
 telescope settled down and behaved perfectly for observing.  During
 a period of better seeing, I determined that the DIS red
 spectrograph focus is just beginning to disagree slightly with the
 slitviewer and blue spectrograph focus, so a seasonal focus
 adjustment will be made soon.
