              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Mostly clear all night with good to excellent seeing.
After further examination of the problem of DIS blue spectral shifts, we
managed to avoid any shifting tonight by keeping the instrument rotation
between -160 to 0.  The diagnosis of the problem also indicates an
approach to a solution, although it remains to be seen how complicated
this will be.
No other problems tonight with telescope or instruments.
