Hi bug-gnu-emacs, Here is an updated M-x lunar phases that displays lunar and solar eclipses. I created this from lunar.el and lunar.el.ncs using diff -cw. I'm attaching output. I was motivated to do this while observing the lunar eclipse of April 4, 2015 in Oklahoma.

Please send this in the form of a patch plus explanation of changes to bug-gnu-emacs@gnu.org. One way to create the patch is diff -cw lunar.el.ORIGINAL lunar.el.YOURVERSION Even better is to base your patch on the current git version; http://savannah.gnu.org/git/?group=emacs .
