                 ------------- ACTIVITY LOG --------------
 Observing Specialist: Noel Camron Hastings
    I opened the dome tonight at 18:30 to allow cooling but closed again
so the first team could take flats with GRIM. I then opened again at
20:15 MDT. After heroic efforts today, GrIm appears to be working again
so we ran with it.
    Don York brought a group of new faculty to train on the telescope
tonight so much time was spent with the initial tours. Grim ran smoothly
all night for the Princeton team.
    We switched to the Echelle at 01:00 MDT and used a new Remark (2.71c)
to test out the auto guiding features that Bob Lowenstein was working on.
We also took time to train the many trainees.
    All Echelle observations ran smoothly all night.
