              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Another beautifully clear night, this time with some periods of good
seeing!  At the start of the night seeing was around 1.2, then in the
middle of the evening it was 0.5-0.6 arcseconds on the echelle slitviewer.
 During second half with Agile (using a blue filter) it was more like
1-1.5 arcseconds, and with APOLLO (using a green filter and at high
airmass) it was worse than 2 arcseconds.  But it was nice to get the good
images while they lasted!
Agile was still having a rotator difficulty, but fortunately the targets
were in the area where the rotator was happy, and everything went very
smoothly.
APOLLO finally got some good data after work done on the instrument
earlier in the month, and at first look it appears that the work brought
some real improvements in detector behavior.  We were also very happy to
have >0 measurements for this lunation; we had been thinking it might be
worse than July.
