The 
Bartlesville Astronomical Society meets monthly to share experiences, exchange information and learn about the fascinating and ever changing world of astronomy.  Our members conduct public star parties (observing sessions), providing the opportunity for everyone to see the celestial wonders of the night sky through telescopes and binoculars.  But you don't need a telescope to join.  The Bartlesville Astronomy Club is open to anyone with an interest in astronomy and a desire to learn.

If you have an interest in astronomy, we encourage you to join the Bartlesville Astronomical Society.  Whether you're curious about stars and constellations, planets, asteroids and comets, solar or lunar eclipses, black holes, galaxies, meteor showers or any other aspects of space and astronomy, the Bartlesville Astronomical Society has something to offer.


For most of human history, the stars told us where we were in space and time.  Have we forgotten how to look up?

Contributing to Science by Observing Occultations

Citizen Science is a broad topic that includes many ways that amateurs can contribute to professional science through observations, data collection and data analysis, in a wide variety of scientific fields.  Astronomy is one of the fields in which citizen science has a long and respected history.  Until around the turn of this century most comets and many asteroids were discovered by amateurs.  Amateur variable star observations and lunar and planetary observations have long provided critical data to professional astronomers.

Amateur observations of lunar and asteroid occultations have played in increasingly important role in advancing our understanding of lunar motion, lunar topography, asteroid orbits, and asteroid shapes and sizes, as well as stellar properties and double star detections.

Making occultation observations is well within reach of the typical amateur astronomer.  The equipment required can be as simple as a timing device (a stop watch in the old days) and a notebook for recording timings.  Any amateur astronomer, in the right place at the right time, can make important contributions to science by observing occultations.
