Hi Glenn,

You are right. I have a bug. Two conditions must be met -- the lunar
latitude must be near 0 AND the phase must be full e.g. longitude.

Code should read,
   (if (or (= phase 0)
            (= phase 2))
        (cond ((< moon-lat 2.42600766e-1)
               (concat "** " phase-name " Eclipse **"))
              ((< moon-lat 0.37)
               (concat "** " phase-name " Eclipse possible **"))
              (t
               "")
              )
      "")
    )
I will send a new patch/diff file.
