(meteorobs) Plotting chart wanted for Levy comet/radiant

[Luc Bastiaens]

Hi John,

The Atlas Brno by Vladimir Znojil contains gnomic maps for the whole
sky, including the southern hemisphere.  Unfortunately, the atlas is
out of print, but we made the charts available for download at
http://www.imo.net/files/data/brno/

However, when printing, make sure the accuracy of your printing device
is good enough to allow correct measurements.  See
http://www.imo.net/visual/minor/gnomic/measuring for the explanation.

Still hoping for a miraculous change in weather here for tonight, but
it looks pretty bad...  Good luck for the Aurigids everyone!

Cheers,
Luc
