Greenwich Astronomy

Astronomy / April 15, 2019


The Observatory is operated by members of the Astronomical Society of Greenwich on behalf of the Greenwich Board of Education. The Observatory is on the grounds of the Julian Curtiss School, East Elm Street, Greenwich (see map below), and is open to the public free of charge twice a month, and for special celestial events. The Observatory is also open by appointment for group visits, and we welcome the opportunity to acquaint area teachers, students, and parents with the joys of amateur astronomy. Open the 1st and 3rd Wednesdays of every month (if skies are clear). Spring/Autumn 8-10 PM Summer 9-11 PM Winter 7-9 PM


Alden W. Smith, a science teacher at Greenwich High School, built the Bowman Observatory in 1940 as a teaching facility; it is owned by the Greenwich Board of Education. When the Astronomical Society of Greenwich was formed in 1984, the Observatory had not been used for some time and needed considerable work; also the telescope was damaged beyond repair. Members of the Society took on the project, including installation of a 12 1/2″ Newtonian Reflector telescope that was named in honor of Alden Smith. The Observatory was reopened in 1986 so it could be used again for Greenwich school students and the public.


In 2007, the town of Greenwich funded replacement of the old dome with a motorized Observa-dome that rotates 360 degrees.

Thanks to the generosity of several donors, in 2014 The Astronomical Society of Greenwich installed a state-of-the-art RCOS Carbon Truss 16″ Ritchey-Chretien F/8.4 telescope in the Observatory. This new telescope allows increased, easier usage by Greenwich school students, and it substantially increases the number of sightings visitors can enjoy on public nights.

The old 12 1/2″ telescope can now be used for special events and community outreach.
