NOTICE TO USERS
Commander, Naval Meteorology and Oceanography Command is consolidating the command's web presence in accordance with Department of Defense (DoD) and Navy guidance. The U.S. Naval Oceanography portal will be the single access point for all public facing Meteorology and Oceanography products and services. This publicly-accessible portal is currently online at http://www.usno.navy.mil and is being populated. In the near future, non-DoD users will be redirected to this portal.
DoD customers can access all operational data, products and services via the NIPRnet Naval Oceanography Portal site at https://oceanography.navy.mil (CAC required).
Astronomical data are sometimes needed for civil or criminal court proceedings, especially where there is an issue of the amount of natural illumination available during the incident in question. Both astronomical and meteorological information may be needed in such cases.
The U.S. Naval Observatory does not collect or maintain records or systems of records of astronomical phenomena - for example, observed times of sunrise, sunset, twilight, or Moon phases - that might be useful for litigation. Such observations are not regularly made by any agency of the U.S. government, since the relevant data can be computed for past or future dates to sufficient accuracy for all practical purposes. In this sense, astronomical data is quite different from weather data, which must be observed and recorded. These kinds of astronomical computations can usually be performed by any observatory, planetarium, university astronomy department, or other competent authority.
The Astronomical Applications Department of the Naval Observatory provides Web pages where these calculations can be made online. For example, the Web page titled Sun and Moon Data for One Day provides sunrise/sunset, moonrise/moonset, and twilight times along with Moon phase for any specific date and place. Other astronomical information can be found in the department's Data Services pages. There is no charge for these data services.
The Naval Observatory also can provide, by mail, tables of sunrise/sunset, civil twilight, or moonrise/moonset times for a specific location, for an entire year. Each table produced for mailing costs $15.00, which must be prepaid by check or money order. Download the order form, fill it out, and return it to the Naval Observatory along with payment.
If a litigant desires a signed letter or some other type of "certified" document containing the calculated data, there are several private sector sources that can be used. Resources that can assist you in finding information and expert testimony are listed below under Forensic Services.
