Quick hack just parsing the output of diary-sunrise-sunset.

I added this early in my org-config file (which is sourced by .emacs)
- modify latitude, longitude to taste:

--8<---------------cut here---------------start------------->8---
;;; diary supplement - rich in Ca
(setq calendar-latitude 42.3)
(setq calendar-longitude -71.0)
(defun diary-sunrise ()
  (let ((dss (diary-sunrise-sunset)))
    (with-temp-buffer
      (insert dss)
      (goto-char (point-min))
      (search-forward ",")
      (buffer-substring (point-min) (match-beginning 0)))))

(defun diary-sunset ()
  (let ((dss (diary-sunrise-sunset))
        start end)
    (with-temp-buffer
      (insert dss)
      (goto-char (point-min))
      (search-forward ", ")
      (setq start (match-end 0))
      (search-forward " at")
      (setq end (match-beginning 0))
      (goto-char start)
      (capitalize-word 1)
      (buffer-substring start end))))
--8<---------------cut here---------------end--------------->8---

and this to one of my agenda files:

--8<---------------cut here---------------start------------->8---
#+CATEGORY: Weather
%%(diary-sunrise)
%%(diary-sunset)
--8<---------------cut here---------------end--------------->8---

and I get:
