              ------------- ACTIVITY LOG --------------
Observing Specialist: P.Gaulme
We tracked down and corrected a light leak in DIS (red channel), which was at the connecton between the instrument and the camera.
The weather was perfect, except when we started Apollo: some light clouds perturbed the measurements.
We noted an odd 40-arcsec pointing jump during Apollo. For this, Russet will invstigate in more details.
