                ------------- ACTIVITY LOG --------------
1st Half Observing Specialist: G.Saurage
Clear skies but terrible seeing.
Echelle slitviewer died around GMT 4:54 with ecamera giving timed out
errors. Timbuktu could not talk to the Slit computer. Slitty was
power-cycled and everything came back. Seeing continued to be troublesome
for the slitviewer to stay on guiding.
2nd Half Observing Specialist: R.McMillan
Toward the end of first half, the observer was having trouble getting
anything due to the poor seeing; manual guiding was necessary.
Seeing also hampered APOLLO; although it improved from awful to
merely poor by the end of the APOLLO run, we got no returns.  The
final echelle run had variable seeing, sometimes almost reasonable
and sometimes bad enough to cause guiding problems.
I made lots of progress on the Q2 schedule and other paperwork.
