San Juan Capistrano. Fall. 1973 March15, between midnight and 4 am PST. Meteorite type: H6, ordinary chondrite. Two specimens with a total mass of 56g were recovered. Location: 33°29'05''N, 117°39'45''W. The largest piece, 50.5g, penetrated the aluminum sheeting roof of a carport in a mobile-home park and was picked up on the carport floor several hours later. The second smaller fragment, 5.5g was discovered about one month after the fall in the gutter of the carport roof. Source: Meteoritical Bulletin 53, p. 138-139; R. C. Finkel, D. Lal, K. Marti (1973).
