Any reason why the "Download this Document" link has been removed? I always prefer to print the clean PDF version of Phil's articles for taking into the field.
Hopefully its just a minor oversite.
Thanks again Phil for another great article!

Yes, oversight on my part. It's there now.

For the record, the fact that Ophiuchus is a zodiacal constellation has nothing to do with precession. Precession changes the position of the celestial equator, but not of the ecliptic. Ophiuchus was a zodiacal constellation when Claudius Ptolemy codified modern astronomy and astrology, just as it is today.

Which, of course, makes the "discovery" of Ophiuchus in January 2011 all the more of a non-news story.
