                ------------- ACTIVITY LOG --------------
 Observing Specialist: R.McMillan
 The night was clear with unstable, often poor seeing.  Velocity
 scales were unchanged during afternoon checkout.
 APOLLO got reasonable data in spite of the variable seeing.  When
 the tertiary was moved back to NA2, it was too far off to close the
 clamp.  Recovery only required homing the tertiary, but took a
 little longer than usual because I was also trying to help the users
 with script implementation at the same time.
 As discussed in previous phonecons, I focused in one broad and one
 narrow filter in order to look for inconsistencies in focus among
 the narrowbands.  The two measurements did disagree with each other
 by 25 microns, but I really felt the difference was due to seeing
 variation and no real conclusions about filter focus could be made;
 therefore, I recorded only the narrowband focus for posterity.  This
 effort will be continuing, especially in better seeing conditions.
 Second half, DIS was more severely affected by the seeing than
 NICFPS, but the science targets were extended anyway.  Telescope and
 instruments behaved well.
