The Astronomical Society of the Pacific (ASP) was founded in 1889 by a group of Northern California professional and amateur astronomers after joining together to view a rare total solar eclipse. The ASP's earliest purpose was to disseminate astronomical information -- a mission which has flourished with astronomers' inexhaustible exploration of the universe. The ASP has become the largest general astronomy society in the world, with members from over 70 nations. The ASP Board of Directors and the Advisory Council are comprised of members of the astronomical, educational, and amateur communities.
The mission of the Astronomical Society of the Pacific is to increase public understanding and appreciation of astronomy through scientists, educators, enthusiasts and the public as a vehicle for advancing science literacy and exchange.
