(meteorobs) Draconids visibility map

[Geert Barentsen]

Hi all,

I plotted a simple "visibility map" for the Draconids radiant tonight
using the fabulous Python programming language (+ the popular
libraries "PyEphem" and "Matplotlib"):

( from http://www.imo.net/draconids2011 )

I thought it would be fun to promote Python by sharing the source code
use to create this map (just 50 lines!):

Please do point out any mistakes :-)
