              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Frustrating weather - approaching rain but never more than a few drops,
clear skies with nearby radar, or cloudy skies with no precip threats.
Finally mid-morning it cleared up properly and we got some actual work
done.
We saw some oscillations of the altitude axis on circumpolar targets.  It
was enough to make the stars look visibly elongated in good seeing
conditions - the seeing for Tspec in the focus log should have been much
better.  But I don't think it was affecting guiding, because whenever the
guiding was off it seemed to be closer to the azimuth direction.
