With over 50 years of uninterrupted service under its belt, the Lowell Observatory’s 21-inch, equitorially mounted Cassegrain Reflector remains productive in monitoring the variability in brightness of Uranus and Neptune. With fully robotic photometric telescopes now taking over much of the type of research pioneered by the telescope, the future of this historic workhorse is in question. Nevertheless, it continues to fill a niche. Astronomers at the Lowell Observatory are positioned to assemble the most complete decades-long seasonal picture of how Uranus varies in brightness as the planet, on its 84-year long trip around the Sun, reaches equinox and the Sun crosses its equator from South to North.
