Hi,
before the show begins tonight, a short report from my last observation as of
19/12/2007. One of the plots can be traced back to the URS radiant quite
well.
Wishing you clear skies for the rest of the evening (here it doesn't look all
too promising, given the combination of haze and a close-to full moon)...
Daniel

Comments: Kind of crisp conditions with cold, clear skies
even from Munich. Moon disturbing, apart from the cold that
sent me in again after this hour.
