                ------------- ACTIVITY LOG --------------
 Observing Specialist: N. Ule
Night started with patchy clouds to the south which moved north.  First
observer managed to work around holes in the clouds.  Had some problems with
pointing on the echelle.  Managed to fix that partway through A-half with
assistance from Russet McMillan.  Second half observers ran smoothly.
