This page is dedicated to the long, 18 plus year, campaign conducted on the longest know eclipsing binary star having a period of approximatly 27 years.
The data contained hein was obtained using the Phoenix-10 telescope at the Fairborn Observatory, operated and maintained by Louis J. Boyd. The principal observer (PI) during the entire proect was Dr. Robert Stencel. The data being presented here is in its RAW form so that it can be preserved without interpretation or mainipulation. I direct your attention to the offical web site for this specific project located at:
The reader is also refered to Chapter 13 in the book "Small Telescope & Atronomical Research, 2010. Eds Genet, Johnson, & Wallen" for the complete description of these data presented here.
