From the Observatory’s website:
“Free public star parties are held monthly at Griffith Observatory from 2:00 p.m. to 9:45 p.m. with the assistance of volunteers from the Los Angeles Astronomical Society, the Los Angeles Sidewalk Astronomers, and The Planetary Society.
“They are a chance for the whole family to look at the Sun, Moon, visible planets and other objects, to try out a variety of telescopes, and to talk to knowledgeable amateur astronomers about the sky and their equipment.”
