On Tuesday February 11, we’ll be hosting a talk on Celestial Navigation by former WSA member Elbert “Ash” Ashbaugh. Before your eyes glaze over at the thought, Ash wants to stress there will be no spherical trigonometry, no space coordinates. But there will be Babylonians, Vikings, the English, and why noon isn’t 12 o’clock. You’ll get to see a Viking sun stone, a sextant or two, and why all you need is the sun at noon, Polaris at dusk and dawn.
Celestial navigation, also known as astronavigation, is the ancient and modern practice of position fixing that enables a navigator to transition through a space without having to rely on estimated calculations, or dead reckoning, to know their position. Celestial navigation uses “sights”, or angular measurements taken between a celestial body (e.g. the sun, the moon, a planet, or a star) and the visible horizon to locate one’s position in the world, on land as well as at sea. The Sun is most commonly used, but navigators can also use the moon, a planet, Polaris, or one of 57 other navigational stars whose coordinates are tabulated in the nautical almanac and air almanacs.
Ash has sailed and taught sailing for over 25 years in the US, Caribbean and Europe while pursuing a career in computer science and high-tech management. He has been a WSA member and is currently the Director of Field Operations for the American Sailing Association.
