                ------------- ACTIVITY LOG --------------
Observing Specialists: R.McMillan
Thin clouds all night until just before dawn; moderate seeing.
Everything worked like a dream, even mounting Triplespec.  The
Chicago observer struggled with clouds during acquisition but said
the spectra came out quite useful.
