Satellite Watching in Mill Valley
Best Viewing Season
Year-round, best April–October
Weather Conditions
Southern California is one of the clearest regions in the US. Northern California gets more winter rain. The Central Valley can have tule fog in winter but is otherwise clear.
Light Pollution
Mill Valley has a Bortle class of 5 (moderate light pollution — bright satellites easily visible). The California region averages about 160 clear nights per year.
Launch Visibility
Not visible from California.
Central and Southern California residents can see Vandenberg launches! Launches from VSFB travel south over the Pacific and are spectacular during twilight, creating the famous "space jellyfish" effect visible across most of SoCal.
Viewing Tips for Mill Valley
Despite the clear skies, light pollution is intense along the coast. Head to the desert (Joshua Tree, Death Valley, Anza-Borrego) or the Sierras for dark skies. Vandenberg launch viewing is a unique California perk.
Best Time to Watch
Check for passes during the first 2 hours after sunset or before sunrise. This is when satellites catch sunlight against a dark sky.
What to Look For
Satellites look like steady, bright stars moving smoothly across the sky. They don't blink like airplanes.
