The Delaware Valley Amateur Astronomers is a group of enthusiastic hobbyists who live in and around Philadelphia, Pennsylvania, USA. We love to share our knowledge and enjoyment of astronomy with other amateur astronomers and with the general public.

The DVAA's monthly meetings are free and the public is invited to attend. Meetings always feature a short talk on "what's up" in the sky currently, as well as a talk by a professional astronomer or members of the DVAA or a neighboring club. Meetings also provide time for informal socializing, picking up information sheets from the "freebie" table, and browsing the club's sales table and lending library.

The club holds free public star parties every four weeks from April through November at Valley Forge National Historical Park near Philadelphia. The club also runs classes and clinics that provide an opportunity for one-on-one interaction between new and experienced hobbyists.

Please see our Benefits of Membership page for more information.

The POLC acts through advisory services to local government and through public education. Its goals are to minimize energy consumption, eliminate "waste lighting", minimize light trespass, and provide better aesthetics and visibility at night by improving outdoor lighting design, installation and operation.
