It takes too much time to constantly update a list of papers published. Clicking here takes you to the latest search on the Smithsonian/NASA Astrophysics Database. This is not a comprehensive list as some papers, including the latest are not scanned into the abstract service.

I have been an amateur astronomer for over 4 decades, joining the Riverside Astronomical Society in 1974.  Since 1999, when I attended the Minor Planet Amateur-Professional Workshop at Lowell Observatory,  I have been active in asteroid research.  Since then I have determined over 750 asteroid lightcurves and has published or co-published over 250 research papers, articles and announcements. 


In addition to my research on solar system objects, I like to travel around the world to see solar eclipses.  I have seen 16 Total Solar Eclipses, 3 Annular Solar Eclipses, 6 Partial Solar Eclipses, and 16 Total Lunar Eclipses.


I am the current Treasurer of the American Association of Variable Star Observers (AAVSO), I serve on the Board and am Treasurer of the Society for Astronomical Sciences, Inc., a 501(c)(3) organization whose purpose is to conduct seminars on Pro-Am collaborations.  In 2011 I retired from the Board of Directors and as Treasurer of the Riverside Telescope Makers Conference, Inc. (RTMC) and was the past President and past Treasurer of the Riverside Astronomical Society.  


I became a Full Member of the American Astronomical Society and a member of the Division for Planetary Sciences.  Finally, I am President and CFO of MoreData!, Inc., an organization created to manage research grants from NASA and the National Science Foundation for research scientists. 


Asteroid (39890) Bobstephens was named by the International Astronomical Union.  I also received the G. Bruce Blair Award from the Western Amateur Astronomers for many years of contribution to amateur astronomy.  In 2009, the American Astronomical Society awarded me the Chambliss Award for Amateur Achievement. And in 2012, the Riverside Telescope Makers Conference awarded me the Clifford W. Holmes Award for major contributions in popularizing astronomy. Finally in 2013, I received a Shoemaker Grant from the Planetary Society in support of our work at CS3.
