Have information we can use to flesh out or correct this record let us know. This description of a site outside SERC has not been vetted by SERC staff and may be incomplete or incorrect. Other materials include tools to create synthetic views of Earth and other solar system bodies, tables and tools for the dates of Earth's seasons, celestial navigation data, and links to other astronomical and celestial information. Naval Observatory (USNO) provides a wide range of astronomical data and products, and serves as the official source of time for the U.S. The US Naval Observatory has deployed their monster Precision Measuring Machine to digitize photographic plates covering the whole sky and creating the above map. Explanation: Here lie 526,230,881 of the brightest stars known. Mars moons were discovered in August of 1877 by Asaph Hall at the US Naval. I compared your predicted moon dates with the US Naval Observatory data.

Black Moon: May 19 (third New Moon in a season with four New Moons) Super Full Moon: Aug 1. There is a section of lunar data that includes dates of its primary phases, a tool for calculating the illuminated fraction, and a graphic that displays the apparent disk (the current appearance) of the moon. The United States Naval Observatory performs an essential scientific role for the United States, the Navy, and the Department of Defense. The United States Naval Observatory (USNO) data services page provides tools for calculating the times of sunrise, sunset, moonrise, moonset, and civil twilight, as well as rise and set times for major solar system objects and bright stars.
