The Mount Versant Observatory is a scientific outpost on the planet Denea presumably on or around Mount Versant. It seems to be relatively near Lyneea's home as she has been involved in at least two U.E.O. sightings seen by the observatory. One of these involved an alleged sighting that turned out to be nothing more than a terrestrial anomaly. The next sighting, however, occurred a cycle later and proved to be the genuine article.
