The Analemma Society, in conjunction with the Northern Virginia Astronomy Club volunteers, conducts Friday night observing sessions from 7:30 pm to 10 :00 at the Roll Top Observatory. The sessions start with an introduction to the night sky, pointing out major constellations, the planets, and deep-sky objects. These include a description of the daily motions of the sun and the changes of the seasons. When the moon is visible, a close look at its geological surface features is provided. Views of features of the visible bright planets and their satellites are provided. A wide range of deep-sky objects including galaxies, nebulae, and star clusters can be seen in the telescopes on the site, as well as double stars and other peculiar stars of interest. Viewing of the passage of earth orbiting satellites is provided as the opportunity arises. Sky programs providing a description of the night’s viewing will be provided. See R963 Astronomy and the Modern Social Concept of Time for more information on the lecture.
