Astronomical Data for North Texas

The U.S. Naval Observatory (USNO) computes astronomical data.  Therefore, the NWS does not record, certify, or authenticate astronomical data.  Computed times of sunrise, sunset, moonrise, moonset; and twilight, moon phases and other astronomical data are available from USNO's Astronomical Applications Department (http://aa.usno.navy.mil).  See http://aa.usno.navy.mil/faq/docs/lawyers.php for information on using these data for legal purposes.
