Astronomical Data

Sun and Moon Tides and Currents Time

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://www.usno.navy.mil).

See U.S. Naval Observatory - FAQ - Litigation for information on using these data for legal purposes.
