                ------------- ACTIVITY LOG --------------
 1st half Observing Specialist: W.Ketzeback
 We were closed during twilight because of high dust counts. They dropped
 enough that we were able to get on sky by 20:15. Around 21:00 the echelle
 slitviewer crashed but I was able to recover in under a few minutes.
 2nd half Observing Specialist: R.McMillan
 There were some difficulties with APOLLO, but we did get returns
 despite poor seeing.  After that, the echelle work went very smoothly.
