                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 The night was mostly clear, with good to very good seeing (0.7 with
 echelle at start of second half).  Everything worked well; the DIS
 focus adjustment appears to have been successful.  Echelle pointing
 was very good.  APOLLO got returns despite high airmass, and also
 learned more about reasons for not getting returns on previous runs.
