Please build pyephem for EPEL8. It's a dependency of another package that I maintain and was requested to be added to EPEL8. Feel free to add me (fab) as co-maintainer if you don't want to do it yourself. Thanks.
This bug appears to have been reported against 'rawhide' during the Fedora 32 development cycle. Changing version to 32.
Package is now python-ephem
