The Astronomical Phenomena is a small, useful booklet that contains general interest material pre-printed from The Astronomical Almanac. It is published jointly by the U.S. Naval Observatory and His Majesty's Nautical Almanac Office with information for the year that is two years in advance of its publication date.
