              ------------- ACTIVITY LOG --------------
Observing Specialist: R.McMillan
Clouds all night - impenetrable during first half and semi-permeable second half.  The middle program got just a short time on sky but one usable exposure; the third program struggled for hours but gathered at least a few photons in each exposure.
ARCSAT never opened but did take enough cals to see that things were functional, including reasonable pointing at the flat field screen.  So hopefully next time it gets on sky the star pointing will be okay too.
