SEA to Host Lecture on Celestial Navigation

SEA Semester

Celestial navigation is an important skill taught to and practiced by SEA Semester students.

Sea Education Association (SEA) will host a public lecture, “Introduction to Celestial Navigation” on Sunday, Dec. 3, at 2 pm.  Virginia Land McGuire, SEA Associate Dean for Financial Aid and Student Services and Associate Professor of Nautical Science will deliver the lecture, the final of SEA’s Fall Lecture Series. The lecture will be held at James L. Madden Center Lecture Hall, Sea Education Association, 171 Woods Hole Road, Falmouth. It is free and open to the public. Light refreshments will be served.

About the Lecture
For centuries navigators have used simple instruments and somewhat complex mathematics to determine their location on the globe.  Over the years, the availability of tabular data has simplified the math, yet the mechanics & methods of the celestial navigator remain inscrutable to many.  Join us for an overview of the basic theory and practice of celestial navigation.  We’ll talk about how celestial navigation works, who uses it and why this seemingly arcane skill remains highly relevant today.
