This reference Catalog of Cometary Orbits represents the orbital parameters of hundreds of comets from over 100,000 observations at the Arkansas Sky Observatories (ASO) since 2002, when digital recording of data began at the observatory. Over 250 individual comets are presented with orbital parameters derived from observations solely obtained at ASO, using the three privately owned robotic observatories. Orbital elements are given for 118 periodic comets and 116 non-designated (un-numbered) comets observed by the Observatories during the past fifteen years. Accompanying some of the orbital pages are original photographs from the robotic telescopes at ASO, many times demonstrating the morphology of unusual or in some cases highly common comet types. Established in 1971, Arkansas Sky Observatories is one of the nation's oldest independent non-publicly funded observatories still in operation, providing daily research into asteroids, comets and cataclysmic stars throughout the Heavens.

This catalog is the first in-depth investigation of comets that were reported since the 17th century, but not confirmed and subsequently lost. Volume I of this two-volume work covers objects observed between 1600 and 1899, a period that was dominated by visual observations and was experiencing a rapid evolution in science. The book uniquely combines the history and culture of comet hunting and discovery with modern tools of orbital mechanics to present a wholesome catalog of unconfirmed and suspected comets. Each case includes a presentation of the observations, a discussion about the observer (when possible), consideration of the historic context, and a conclusion as to the nature of the object. In most cases, the book presents material from original sources, including some never before published that were acquired from observatories, libraries, and historical societies around the world. Although some of these unconfirmed comets turned out to be misidentifications of planets or star clusters, fabrications, or poor observations of comets that were already being observed, the Authors did identify many objects that were likely real comets. In some cases, the Authors were even able to derive orbits for the first time. These observations may be valuable in the future, as they could prove to be observations of periodic comets still to be discovered.
