              ------------- ACTIVITY LOG --------------
Observing Specialist: G.Saurage
Thin clouds most of the night, good seeing.
Echelle slitviewer has a high background. It looks like a light source from the
right but it's not. This condition existed before shutdown but it seems worse and
was quite noticable during dark time tonight.
