One way to accomplish this is with a custom skip function and a custom
agenda command. In order for this particular setup to work, you'll need
to put the sunrise sexp in it's own subtree, as in:

--8<---------------cut here---------------start------------->8---
* Sunrise
  :PROPERTIES:
  :CATEGORY: Sunrise
  :END:
&%%(diary-sunrise-sunset)
--8<---------------cut here---------------end--------------->8---

Note: it's important that you use the CATEGORY property to ensure that
the category "Sunrise" is limited to a single subtree.

Then, you could add the following function to your emacs:

--8<---------------cut here---------------start------------->8---
(defun my-org-skip-sunrise ()
  (if (and (not (equal date (calendar-current-date)))
	   (string= (org-get-category) "Sunrise"))
      (org-end-of-subtree t)
    nil))
--8<---------------cut here---------------end--------------->8---

Finally, you could define a custom command that instructs org to use the
skip function to bypass all "Sunrise" entries for days other than today:

--8<---------------cut here---------------start------------->8---
(add-to-list 'org-agenda-custom-commands 
	     '("x" "My agenda" agenda ""
		((org-agenda-ndays 7)
		 (org-agenda-skip-function 'my-org-skip-sunrise))))
--8<---------------cut here---------------end--------------->8---

If you're feeling brave, you could disregard the docstring for
org-agenda-skip-function and bind the variable globally (i.e., invoke
my-org-skip-sunrise on all agenda commands), but I wouldn't recommend
this.

Hope this helps,
Matt
