              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
A clear night with moderate seeing, very productive.  No real problems.
The second half observer was puzzled by some change in the echelle spectra
since August 12 - a wavelength shift which isn't excessive but enough to
cause some difficulty with extraction, and a reduction in the brightness
of blue flats (but not red ones).
