Hi all,
I just wanted to report that I found a very nice astronomy program
called "XEphem", which would make a worthy addition to SL's
repositories, provided its licence isn't a show-stopper.
Although not GPL'd, it used to be in TUV's repos around version 5
pre-EL. It's open source and free for personal and educational use.
Anyway, I was able to build it from source without a hitch (you'll
probably need package openmotif-devel installed).
XEphem site with lots of screenshots:
