Expert Tips for Pico Rivera Observers
When observing from Garvey Ranch Observatory, try to position yourself facing away from the nearest major light dome. For Pico Rivera residents, this usually means looking toward the rural horizons of CA to capture the lowest magnitude stars that are normally invisible from the city center. Scientific Context: While local conditions vary, the instrumented reading of Bortle 7 at Tuna Canyon Park (30.1 miles away) remains the benchmark for regional sky quality.
