Old education-astronomy entry

[Ole Streicher <debian@liska.ath.cx>]

Hi Andreas and Petter,

For the Debian-Astro Blend, I am trying to incorporate the
edu-astronomy task, which surprisingly contains some "Ignore"
entries. Digging into the history [1], they are commented by
Petter as

- Add astronomical-almanac, lightspeed, openuniverse and
  cl-geodesics as ignores based on suggestion from Andreas Tille
  and his Debian Science talk. 

This was back in 2007; however do you still remember what you
suggestion was?

Best regards

Ole
