              ------------- ACTIVITY LOG --------------
Observing Specialist:    R.McMillan
We had thin clouds at the start of the night which looked like they
would pass off later.  So I started with in-dome tests of the SPIcam
shutter behavior, which now appears to be working correctly.  I went
on sky with thinner clouds, but the focus or seeing did not seem
stable enough to do the DIS spectrograph focus test.  So I checked
and corrected pointing with the echelle and did some spectra as well
to test stability since we've been seeing some irregularity in the
echelle biases.  I returned to DIS, and now seeing appeared more
stable although still not very good.  I started the DIS focus test,
and thick orographic clouds moved in an stuck around for many hours.
I was not able to do the APOLLO APD alignment on the moon, nor did I
get any fastcam data.
