              ------------- ACTIVITY LOG --------------
Observing Specialist:    J. Huehnerhoff
Heavy cloud cover with some holes but not enough to justify opening.  A
break in the clouds allowed opportunity to open and some science data was
taken.  Around 20:00MST the cloud cover became to thick to observe through
and the telescope was closed.  Light Snow starting around 4:00MST with
humidity spiking around the same time.
Noticed wandering of star in the azimuth direction at an az of 233 and an
alt of 62.  Star appeared to be moving around more than normal while
guiding with the echelle slitviewer.  This occurred at UT01:26.
