United Astronomy Clubs of New Jersey (UACNJ) is a consortium of amateur clubs from the tri-state region. Our mission is to promote the sharing of resources and information among these clubs, to operate the Jenny Jump Observatory and Education Center, and to promote activities, education, and public awareness in astronomy and related fields.

Free lectures and observing are open to the public every Saturday evening from April through October at the dark sky site in Jenny Jump State Forest. The schedule and other information can be found at programs for Scout groups, schools, etc. can be arranged by contacting [email protected].

UACNJ operates several telescopes at our site, including a 16-inch Newtonian telescope in the Greenwood Observatory, a 16-inch Meade in the Buinis observatory, an eight-inch solar telescope in the Barker Observatory, and a seven-inch Astro-Physics refractor in the Kevin Brady Observatory. Two additional observatories are operated by Member Clubs and are often open on public nights. Enjoy the spectacular views of the sky!

A local architect is currently designing a 16 x 16 foot observatory to house the 25-inch Midkiff telescope. Work on this new observatory will commence this spring.

A joint project with the Center for Solar Terrestrial Research of New Jersey Institute of Technology (NJIT) is underway to install a solar radio telescope and a 48-inch ITEK telescope that will be used for gravity wave research as well as public night observing when available.
