The Bartlesville Astronomical Society welcomes everyone with an interest in astronomy and a desire to learn. Founded in 1958, BAS is an amateur astronomy club open to all levels of expertise. BAS meets monthly to share experiences and learn about the ever-changing field of astronomy. Periodically, we also hold public and members-only star parties (observing sessions), offering everyone the opportunity to view the wonders of the universe.
Our monthly meetings are open to the public and typically take place on the first Monday evening of each month (unless that day falls on a holiday, in which case the meeting date will be changed), starting at 7:00 pm, at the Bartlesville Public Library. Meetings begin with club announcements, current observing highlights, and astronomy news, followed by an educational presentation by a guest speaker who may be a club member or a professional in the field. BAS is a nonprofit organization, run by volunteers and led by an elected volunteer board. BAS is a member of The Astronomical League and the Night Sky Network.
