Re: Moon phases,solver
Thanks Mathias. I would like to reckon moon phases for dates in the past (e.g. AD 1300). What puzzles me is that for full (new) moon separation is less than 180 (0) degrees. I try your suggestion with

Re: Problem after Ubuntu 20.04-->22.04 upgrade
Hello Maxime, I think you need to recompile xephem, to get the libraries right. This is what I did (on Ubuntu 22.10): xephem: apt install build-essential groff-base libmotif-dev libssl-dev
