                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 A peaceful night with no problems.  Several waves of thin clouds
 passed through, with clear patches in between.  Seeing was good
 first half (1.5 at first focus and 1 arcsec an hour later, which I
 missed recording) and somewhat worse (around 2 arcsec) for much of
 second half.  For a change, the humidity was nowhere near the limit.
 JH01 and CU06 made an approved trade between tonight and tomorrow.
